COOPERATION THROUGH TECHNOLOGY:
Michael G. Vannoni and Kent Biringer
Options
for cooperation on the Korean peninsula do exist that could build confidence
and reduce tension. The role of
monitoring technology can help to implement agreements that define, control,
or regulate issues of potential conflict or dispute.
These agreements span a full range of national and international issues
from human rights to resource allocations and national security and can vary
from bilateral arrangements to global treaties or control regimes.
In many cases, elements of the agreement are monitored through the use
of technology to verify compliance or increase confidence among parties that
the terms of the agreement are being met.
Since
the end of the Cold War, the emphasis on regional security has increased
significantly. A widespread
perception exists that without the stability provided by a system of states
dominated

Mr. Biringer has worked at Sandia for 21 years in solar and fossil
energy research, systems analysis, arms control, and nonproliferation.
In
the last two decades, the United States, Europe, and the former Soviet Union
have recognized the vital role arms control and CBMs have played in enhancing
security. Although some states
are uneasy with the concept that arms control and increased openness can
enhance their security, others acknowledge the need to decrease regional
conflict and are beginning to consider new options.
By limiting the numbers and types of military equipment in European
countries, the 1990 Conventional Forces in Europe (CFE) Treaty reduces the
possibility that one country can surprise another with a conventional military
attack. In the Middle East
multilateral peace process, the Arms Control and Regional Security working
group is discussing potential regional arms control and CBMs.
In South Asia, India and Pakistan have implemented a hotline agreement
and negotiated several other military CBMs such as the notification of
military exercises. South America
has contributed to the regional
arms control process with the Treaty of Tlatelolco, which prohibits nuclear
weapons in Latin America, and with the quadripartite agreement for monitoring
nuclear facilities among Brazil, Argentina, the Brazil-Argentina Agency for
Accounting and Control of Nuclear Materials and the International Atomic
Energy Agency (IAEA).
These
regional discussions involve a broad spectrum of issues, ranging from nuclear
arms control to environmental protection.
In the initial stages of regional security discussions, it is important
to identify issues where progress is possible.
Even if the primary regional arms control concern is nuclear weapons,
the first series of discussions may need to focus on less volatile issues,
such as the environment, conventional weaponry, or disaster response.
In regions where tensions are high, limiting armaments or ceasing
controversial weapons development programs may only become possible after
considerable confidence building in other areas.
The following table illustrates potential topics for regional arms
control and CBMs.
Regional vs. Global Cooperation
Many
regional security initiatives occur against a backdrop of multilateral or
global arms control. In such
cases, the question of the relationship of the regional to the global
agreement often arises. Many arms
control analysts emphasize the overriding importance of global agreements,
especially those that concern nuclear issues, and stress that regional
agreements should be embedded in a global context.
However, regional agreements can have advantages over their global
counterparts.

Second,
regional agreements can be tailored to meet particular concerns of regional
parties. For example, a regional
verification regime might be needed for a Middle East nuclear weapon-free zone
to supplement international measures such as those implemented by the IAEA.
Third,
regional agreements sometimes can be negotiated more rapidly than global
agreements. The 1991 bilateral
Open Skies Agreement between Hungary and Romania and the 1989 Wyoming
Memorandum of Understanding on the destruction of chemical weapons between the
United States and the former Soviet Union demonstrate this point.
Fourth,
some issues are purely regional. While
a third party may be requested to monitor compliance with agreements in some
regions, such as the demilitarization of the Sinai between Egypt and Israel,
the Israeli agreement to withdraw from occupied territory is an inherently
regional issue.
It
is important to keep in mind that participation in regional or bilateral
agreements does not preclude participation in global arrangements.
Indeed, a regional or bilateral regime may be a stepping stone or a
necessary first step. It is
possible to imagine a global nuclear weapon dismantlement program for which
bilateral agreements between the United States and the former Soviet Union,
such as START and INF, provide a starting framework.
Long-term
effectiveness of regional security agreements ultimately will depend on the
commitment and day-to-day involvement of regional parties.
Although an external presence may remain important in many regions, it
will not obviate the need for a strong indigenous infrastructure for both the
development and the implementation of region-specific options for arms control
and confidence-building measures. An
institutional infrastructure is needed to support the analysis of policy
options and the process of negotiating agreements. Implementation of agreements will also require a technical
infrastructure that could include the development of monitoring technologies,
a communications network for exchanging information, data-analysis
capabilities, and trained inspectors.
Monitoring
often plays a role in implementing security and arms control agreements.
Monitoring is cooperative when the information is collected, analyzed
and shared by parties to an agreement. Cooperative
monitoring provides a method of openly documenting compliance with the terms
of an agreement and makes any act of noncompliance difficult to ignore.
If technical tools are used to collect relevant information, the
technologies must be sharable among all parties, and all parties must receive
equal access to information acquired by the system. A cooperative monitoring regime also should include
administrative procedures for dealing with anomalous data and false positives.
Such procedures are necessary for constructively resolving disputes
that may arise.
Many
monitoring technologies originally developed for national security purposes in
the United States and elsewhere are applicable to a broad spectrum of regional
arms control and confidence-building applications.
Examples of unclassified and exportable technologies are unattended
ground sensor systems, aerial overflight systems, commercial satellite
systems, and systems for data security and access control.
When combined with data management, analysis, and integration
capabilities, these technologies provide powerful tools for implementing
regional agreements. They enable
parties to observe relevant activities, to define and measure agreed
parameters, to record and manage information, and to perform inspections.
Because
technology plays an important role in implementing agreements, it can be a
particularly useful area for first steps in cooperation.
Although many countries have achieved significant technical
sophistication, applying technology to the cooperative monitoring of security
agreements is often a new concept. For
technically less-advanced countries, achieving familiarity with monitoring
technologies may require significant investment in education and training.
Lack of knowledge about monitoring technology and procedures can
undermine commitment to an agreement and impede effective use of monitoring
technology. Collaborative
projects by regional parties to identify and assess options for technical
monitoring can be significant CBMs.
Experimental
approaches to develop technology to support cooperation are constructive
because they can proceed before formal agreements are in place.
A cooperative monitoring experiment is a technical collaboration on
collecting and sharing data relevant to a monitoring application.
The object is to familiarize participants with monitoring techniques
and procedures. Although valuable
as a CBM, monitoring experiments can also provide information needed by
negotiators during the negotiation process.
Experiments provide the opportunity to investigate monitoring options
in a neutral environment and adjust procedures and technologies to meet
regional needs. Experience from
experiments forms a base for a comprehensive agreement when future political
conditions permit. Interpersonal
relationships resulting from collaboration further support the
confidence-building process.
The experiments on sharing seismic data internationally, conducted by
the Group of Scientific Experts in preparation for the Comprehensive Test Ban
Treaty, is a good example of a large-scale cooperative monitoring experiment.
The
Korean peninsula is the site of one of the world's volatile areas for potential military
conflict as North Korean, South Korean, and U.S. troops face each other along
the 255-km military demarcation line. CBMs,
particularly military ones, that address the security needs of both countries
could decrease the danger of conflict and help create an environment where a
peaceful regime might be negotiated. In
spite of the present mutual distrust, steps can still be taken to prepare for
future development and implementation of CBMs.
Inter-Korean
relations have been quite volatile since the 1953 armistice.
Between 1954 and 1985, North Korea made 205 arms control proposals and
South Korea made 55.1
The proposals included CBMs, operational and structural arms control,
and disarmament. In some cases,
the two countries offered proposals more for political propaganda purposes
than for arms control. Because of
the political conditions in both countries, none of these proposals resulted
in concrete actions. The December
1991 "South-North Agreement on Reconciliation,
Non-Aggression, Exchanges, and Cooperation"
(known as the Basic Agreement) appeared to be a diplomatic breakthrough. The Basic Agreement, which contains provisions for confidence
building, military transparency, and operational arms control, is currently
frozen.
There
is a consistent philosophical difference between South and North Korean
proposals for arms control. South
Korean, European, and American analysts have examined the history of the
Conference on Security and Cooperation in Europe (CSCE) process and promoted
the application of CBMs and operational arms control to the Korean peninsula.
In contrast, Chung-In Moon described North Korean perspectives on arms control
as being based on Europe's
experience during the 1920s, with little analysis of the last 20 years in
Europe.2
The South argues that confidence must be built before structural arms control
or disarmament can occur. The
North argues that arms reduction, primarily in the number of active military
personnel, will result in increased confidence.
Opportunities For Military Confidence Building
A
feature of arms control in Europe that may have application in the Korean
context is transparency. The
fundamental purpose of transparency measures is to share selected information
about activities that previously were shrouded in secrecy.
Transparency does not limit military activities or resources and can be
part of a formal agreement or be performed informally
as a CBM. Techniques to
achieve transparency fall into two broad categories:
nontechnical (declarations, onsite observers) and technical (the use of
sensors to monitor activity, analysis of physical samples).
A benefit to implementing transparency measures is that personal
contact between adversaries helps to humanize the effects of prolonged
hostility.
Ambassador
James Goodby, former Chief Negotiator for U.S./Russian Safeguards,
Transparency and Irreversibility (ST&T) negotiations, assessed the
evolving South-North positions in operational and structural arms control.3
Young-Koo Cha and Kang Choi examined transparency along with other
potential CBMs for the Korean
peninsula.4
Both studies found a number of similarities in the positions of South
and North Korea. South and North
Korea agree on the basic principle of constraining certain military operations
and dispositions. Their differing
views of a threat, however, result in very different applications of that
principle. In spite of these
different perceptions, the two sides agree that:
The
DMZ should be truly demilitarized and made a zone of peace.
Communication
links should be established to avoid inadvertent conflict.
Military
exercises should be declared in advance of performance.
Both
governments should mutually declare their intention to avoid the use of force.
Cha
and Choi concluded that transparency measures, accompanied by some constraint
measures, are the best choice for future initiatives to develop military
confidence between South and North Korea.
They recommended that transparency measures be introduced first because
excessive secrecy about military status can damage relations by fostering even
greater suspicions. Measures that
provide transparency in pertinent areas of military affairs help reduce
suspicions by providing opportunities for communicating nonhostile intentions.5
Although transparency is an excellent first step to take, it does not
solve all security concerns nor does it change military realities.
The goal of transparency should be a balance between secrecy and the
acknowledgment of legitimate mutual security concerns.
To
date, North Korea is resistant to transparency in military matters. Onsite inspections of military activities have been
rejected as an infringement on sovereignty; only strong international pressure
convinced North Korea to provide the IAEA access to its nuclear facilities.
Given the centrally controlled political system in North Korea,
transparency measures that are not carefully defined may be perceived by the
leadership as presenting a threat to the state.
Therefore, proposals to North Korea to implement specific transparency
measures should demonstrate pragmatic benefits.
Including justification of the transparency proposal would help North
Korea recognize the potential benefit of selective openness in military
activities.
Four Conceptual CBMs
Bilateral
contacts between South and North Korea still occur.
The multilateral Korean Peninsula Energy Development Organization
(KEDO) project to build nuclear reactors is progressing.
South Korean companies continue to establish commercial links with the
North. Military confrontation,
however, remains a serious risk. Given
the suspension of direct official talks between South and North, are there
steps that either might take that would contribute to the long-term goal of
building confidence?
Based
on the analysis by Cha, Goodby and others of common themes in South and North
Korean arms control proposals, four conceptual transparency measures for
military activities are presented here. After
the presentation of the conceptual CBM, a first step that South Korea could
conceivably take is defined for each option.
A second step, that could become cooperative, is then defined for each
option.
Opening
dialogue with North Korea is one of the first steps to begin to ease the
current political tensions. For
many years, North Korea rejected direct official interaction with South Korea
because of the implication that it recognized South Korea as a sovereign
entity. Perhaps third parties, such as the news media, can function
both as communication channels and advocates.
An independent review of confidence-building proposals by a credible
third party may contribute to North Korean acceptance.
The Internet offers a new mode of communication that can be performed
discretely and unofficially in presenting perhaps a draft of conceptual CBMs
sent via the internet. North
Korea could then access the information, which may give them some "food"
for thought without the obligation to make comment.
The
analysis of the following and other options for military transparency may
present an opportunity for political confidence building.
North Korean academics and technical experts might be invited to
participate in a joint study of military confidence building options.
Alternatively, North Korean academics could perform such analysis
independently and present the conclusions in a multilateral forum.
Reduce
Dangerous Military Activities In The DMZ
Issue:
Military incidents within the DMZ are a source of tension.
Conceptual CBM: Restrict troops to
observation posts in the DMZ and declare travel to those posts.
Cooperative Monitoring Option: Use
ground sensors to perform the function performed by military security patrols.
Possible First Step: Establish an experiment
to assess performance and reliability of a variety of intrusion detection
sensors in a realistic Korean environment.
Background Comments:
Security
patrols operate routinely in the DMZ. Military
intrusions occur that violate the terms of the 1953 Armistice Agreement.
Such incidents are relatively common and adversely affect bilateral
relations. An accidental
violation of the Armistice may be interpreted as having greater political
significance than the reality. If security troops in the DMZ were restricted to observation
posts, there would be far less potential for conflict between rival patrols.
The security troops would continue to function as observers at the post
and also form a rapid-reaction force to respond to potential violations.
An
experiment in monitoring with sensors would contribute to the development of
options for transparency. There
are several direct benefits associated with monitoring experiments:
Preparation
of options for a time when future political conditions are more favorable
Development
of indigenous technical capability
An
opportunity to assess operational issues in monitoring
Increased
confidence with monitoring technology and procedures
The
experiment should operate for 6 months to a year) to evaluate the effect of
climate and aging on the monitoring hardware.
The experiment should also test alternative modes of communication.
Possible Cooperative Step: Establish
communication links with interested parties and share data from the
experimental system. This step
would serve to acquaint the North Koreans with cooperative monitoring and
transparency. An impartial review
of the experimental system and test results by a credible party could make the
transparency option seem more realistic to North and encourage North Korea to
participate in future experiments.
Figure
1. Example
of Facility for Evaluating Ground Sensors
Transparency
in the Storage of Heavy Weapons
Issue:
Uncertainty about the location and status of heavy weapons raises
concern about aggressive intent.
Conceptual CBM: Declare heavy weapons in
storage sites and announce when weapons leave or enter.
Cooperative Monitoring Option: Monitor
the perimeter around a storage site to detect and report the movement of heavy
weapons leaving or entering.
Possible First Step: Establish an experimental
system at a realistic site to assess sensor system performance and
reliability.
Background Comments: The status and location of heavy weapons (e.g., tanks, artillery,
rocket launchers) are security concerns.
The uncertainty is that an exercise or routine military movement may
transform into an attack. A
declaration of pending movement is a declaratory CBM.
This cooperative monitoring
option supports the declaration by providing transparency into the location
and status of heavy weapons. The
number of, capability of, or ability to use these weapons is unaffected.
Canada pioneered monitoring concepts for stored weapons as a
NATO-Warsaw Pact CBM in Europe.
The
strategy for this experiment is similar to intrusion detection.
Although the type of monitoring sensors will be different, the
experimental system should operate for an extended period to evaluate
performance and reliability. Credibility
in distinguishing significant events from unimportant background activity and
reporting that information to a monitoring center is important.
Possible Cooperative Step: Establish
communication links and share data from this experimental system with
interested parties. The strategy
is the same as dangerous military activities.
Third parties could again perform the role of neutral reviewer of the
experimental system.
Transparency in Military Movements
Issue:
Military movements raise concerns about preparations for attack.
Conceptual CBM: Permit regularly
scheduled or challenge aerial overflights to monitor ground activities.
Cooperative Monitoring Option: Install
commercially available sensors on an unarmed aircraft.
Possible First Step: Perform analysis of
sample imagery to determine what capability is necessary to monitor activities
of concern.
Background Comments: Large military training
maneuvers and movements are destabilizing when there is a low level of trust
between countries. Permitted
aerial overflight provides a means to implement transparency without
restricting capability. Aerial
monitoring is less intrusive and creates fewer political implications than
ground-based sensors or observers. The
Open Skies Treaty between members of NATO and the former Warsaw Pact and the
1991 bilateral agreement between Hungary and Romania are useful precedents.
Several papers have investigated the concept of cooperative aerial
monitoring in Korea.6
A
country contemplating the use of aerial monitoring needs to understand what
technical capability is necessary to make a substantive contribution to
transparency. A useful first step
would be to assess various methods of aerial sensing to decide which ones
should be used. While optical
image resolution is a function of the capabilities of the optics and the
altitude of the aircraft, the Open Skies regime permits no better than 30-cm
resolution. Although the Open Skies Treaty is frequently cited as an example,
the monitoring techniques used were negotiated specifically for that treaty.
The Open Skies Treaty should not be viewed as the only technical
approach. Airborne monitoring
equipment is available commercially today that has greater capability than
that agreed during Open Skies negotiations.
Higher resolution synthetic aperture radar would
be particularly pertinent to the Korean environment due to the presence of
rain, snow, fog, and haze.
Possible Cooperative Step: Publish and distribute analysis of sample imagery.
The concept of permitted and reciprocal aerial overflight for
monitoring is not beyond the realm of possibility since North Korea opened
three commercial air routes over its territory in 1996.
Even if motivated solely by financial remuneration, this action is
unprecedented in North Korea's
history.
Publication
of a South Korean sensor study and imagery analysis would contribute to North
Korea's
understanding of this option for transparency.
The document could be directly or indirectly distributed to North Korea
for review. Third parties can
again play a useful role as independent reviewers.
The
United States performed a similar project for the Open Skies Treaty.
The Defense Special Weapons Agency (DSWA) produced a book containing
actual imagery along with a description of the monitoring equipment and
procedures used to collect the images.7
The United States distributed the book to interested parties to
increase understanding of the Treaty and provide a reference tool.
Transparency
measures are potentially applicable to topics as controversial as the
production of long-range missiles. Both
South and North Korea have an interest in ballistic missile production.
The United States has held bilateral talks with North Korea on missile
development, production, and sales with the goal of persuading it to accept
the guidelines of the Missile Technology Control Regime (MTCR).8 The 1980 ROK-U.S. missile development agreement restricts
South Korean missiles to a maximum range of 180 km.
South Korea has cited the need to modernize its aging ballistic missile
force for defensive purposes. This
program would involve indigenous development and production.
After meetings with ROK representatives in 1996, the United States has
indicated that it would relax the restrictions of the 1980 agreement and
support South Korea's
entry into the MTCR.
Issue:
Production of long-range missiles raises regional concern about
aggressive intent.
Conceptual CBM: The MTCR does not limit
domestic deployment of long-range missiles or reduce regional concerns about
their use. A significant CBM
would be for both South and North Korea to renounce the possession and
production of long-range missiles. Long-range
missiles could be defined by the MTCR guideline of 300 km.
Under this assumption, production of the North Korean SCUD-B missile
and the proposed replacement for the South Korean NHK-2 missile could
conceivably be permitted. North
Korean production of SCUD-C, No Dong, and Taepo Dong missiles would be banned.
Cooperative Monitoring Option: Install
sensors at production facility gates to distinguish between short and
long-range (i.e., over 300 km) missiles.
Possible First Step: Conduct a study to define
the physical characteristics of missile systems that comply with the range
restriction and assess how these characteristics can be detected and measured
by sensors.
Background Comments: Monitoring technology,
given appropriate intrusiveness, can successfully monitor missile production.
The 1987 Intermediate Range Nuclear Forces (INF) Treaty between the
U.S. and the Soviet Union provides a useful precedent for the selective
monitoring and inspections of missile production facilities.
Intrusiveness is the key factor in any missile production monitoring
system. A study to identify and define the physical characteristics
of missiles consistent with the 300 km range limitation would permit
production monitoring options to be identified and proposed.
Possible Cooperative Step: Publicly
demonstrate options for monitoring missile production identified in the study
with a functional model. A "laboratory-scale"
experimental model to demonstrate the procedures and technologies of a
conceptual missile production monitoring system is a visual way to present a
system and prevent
misconceptions. It would also
demonstrate the level of intrusiveness and demonstrate how much transparency
can be achieved. The U.S. built a
detailed and functioning table-top model of a proposed system to monitor
missile production to assist the negotiation process by demonstrating system
capabilities to the Soviets during INF Treaty negotiations (see figures 4 and
5). Models also assist national leaders with gaining insight and
understanding of the monitoring process.
Conclusions
Cooperation
among countries in Asia will be needed to reduce tensions and to solve security
problems. Arms control and
confidence-building measures, both international and regional, could play a role
in reducing threats of nuclear proliferation and conventional military conflict.
Developing an infrastructure to support cooperation will be a complex
technical and political challenge because there is little tradition in this
region for openness about national security activities.
Additionally, countries in the region have relatively little experience
with technologies for implementing cooperative agreements.
Cooperative
monitoring offers an opportunity for countries to engage in meaningful
collection and exchange of information that can increase transparency and reduce
tensions. Without credible
information about relevant activities in other countries, arrangements will not
reduce tensions or alleviate concerns. On
the contrary, they could form the basis for countries to accuse each other of
violations and increase the potential for conflict.
A
number of regional security analysts see opportunities for constructive measures
to decrease military tensions on the Korean peninsula.
To date, political conditions have not permitted the successful
negotiation and implementation of any significant measures.
This chapter presented four conceptual options for CBMs with first steps
that could evolve into South-North cooperation.
These concepts for military CBMs are intended to stimulate discussion and
require further study.
Parties
can experiment with cooperative monitoring concepts to achieve transparency
before entering into either a formal or informal relationship.
Experiments familiarize participants with both the procedures and
technology for monitoring and can be a form of confidence building themselves.
Collaborations can provide neutral ground for interaction among technical
communities and produce results that will aid national leaders in the
implementation of potential future agreements.
Collegial relationships that develop among participants can also
contribute to confidence.
Success
in building confidence is more likely to occur when all parties understand they
will not necessarily be worse off as a result of implementing military
transparency. Explanation of key
concepts and assumptions should be included with proposals.
Alternative means to formal diplomatic exchanges, such as the use of the
Internet, now exist and may permit a quiet, yet effective, process of
information exchange and consensus building.

The MTCR was created in 1987 to define common export guidelines for
missiles and related technologies. The
original threshold for control was ballistic missiles and unmanned aerial
vehicles capable of delivering a 500-kg payload to a range of 300 km. In early 1993, this threshold was lowered to include any
missile believed to be intended to deliver a nuclear, chemical, or
biological warhead.
