The proliferation of chemical, biological, and nuclear weapons is now the single most serious security concern for governments around the world. Peter R. Lavoy, Scott D. Sagan, and James J. Wirtz compare how military threats, strategic cultures, and organizations shape the way leaders intend to employ these armaments. They reveal the many frightening ways that emerging military powers and terrorist groups are planning the unthinkable by preparing to use chemical, biological, or nuclear weapons in future conflicts.

Distinguished specialists consider several states and organizations that have this weaponry: Iraq, Iran, India, Pakistan, North Korea, and Israel, as well as the Aum Shinrikyo cult. The contributors expose plans for using unconventional weapons, highlighting the revolutionary effects these arsenals might have on international politics and regional disputes.

This report reviews Chinese participation in the international negotiations for a Comprehensive Nuclear Test Ban Treaty (CTBT) at the Conference on Disarmament (CD) in Geneva and provides background for China’s decision-making procedures during the negotiations.

The CTBT negotiations marked the first important international negotiations for a multilateral disarmament treaty in which China participated from beginning to end. They were the first important international negotiations in which China, as a nuclear power, had great influence. The Chinese delegation to the CD assumed a serious and responsible attitude during the entire course of the negotiations. In part to increase international confidence that it would sign the CTBT by 1996 as scheduled and in part to indicate its intent to adapt itself to the world trend toward increased international cooperation and nuclear arms reduction, China announced during the latter stage of the negotiations that it would suspend nuclear testing.

As an example of successful multilateral negotiations, the conclusion and signing of the treaty, although long postponed, is an important achievement in arms control. As the sole declared nuclear-weapon state of the Third World at that time and the last among the five nuclear-weapon states (P5) to cease nuclear testing, China’s stance toward the CTBT negotiations was the object of world attention and concern. The population of China accounts for nearly one-quarter of the world’s total; China’s positive position on the CTBT and its contributions toward this end has a major worldwide impact now and in the future.

Prior to the commencement of the CTBT negotiations in Geneva, China declared on October 5, 1993, that while supporting an early conclusion of the treaty it would “take an active part in the negotiating process and work together with other countries to conclude this treaty no later than 1996.” China kept its promise.

China pursued a fair, reasonable, and verifiable treaty with universal adherence and unlimited duration. During the negotiations, China presented many working papers, non-papers, and suggestions regarding the CTBT draft text (including a number of revisions), and dealt with a series of critical issues in the Preamble, Basic Obligations, Organization, Verification, and Entry into Force sections of the treaty. The Chinese delegation played an active role at the conference table, and contributed positively to the weekly P5 consultations that ran in parallel with the CTBT talks.

China adhered toughly to its positions on two issues in the latter stage of the CTBT negotiations. One concerned potential abuses of the on-site inspection procedures. The other was that all nuclear-test-capable states (assumed to be the P5, India, Israel, and Pakistan) must accede to the treaty in order for it to enter into full legal force. Although China was not entirely satisfied with the final draft CTBT, it accepted the treaty. It agreed to sign the CTBT in the belief that the treaty text represented the best achievable result of the negotiations of the preceding two and a half years, reflected by and large the state of the negotiations, and was in general balanced.

Signing the CTBT was in line with China’s consistent stand in support of “the complete prohibition and thorough destruction of nuclear weapons.” This was one of the major reasons China supported an early conclusion of the treaty. Of course, China’s desire to meet the trend of the modern world also motivated it to sign. Because economic development had long been Beijing’s top priority, China needed a peaceful security environment in order to devote itself completely to the modernization of the nation. To this end, its defense buildup had been steadily subordinated to national economic development. Beijing’s decision on the CTBT negotiations stemmed also from its self-defense and no-first-use nuclear policies. China had established an effective nuclear force for self-defense.

China is now making preparations for the treaty to enter into force. After the conclusion of the CTBT, China will continue efforts in pursuit of world peace, development, and cooperation. Meanwhile, China will continuously ensure the safety and reliability of its nuclear weapons without nuclear testing.

A solution to the nuclear dilemma has eluded mankind since the creation of nuclear weapons.  A visionary attempt by the United States to eliminate the threat at the beginning of the nuclear age (the "Baruch Plan" for the international control of atomic energy) fell victim to the Cold War.  However, in this new geopolitical era, the UN Security Council finally has the opportunity to function as its founders intended, and it may now be appropriate to reconsider the idea of a security regime that would bring all nuclear weapons under international control.

The internationalization of nuclear security would have to be implemented over a number of years through a systematic step-by-step process.  This paper suggests the following three-phase approach: in Phase I, a new international security regime would be established; in Phase II, a UN-owned international nuclear deterrent force (INDF) would be created; and finally, in Phase III, all national nuclear arsenals would be eliminated in favor of the INDF.

In recent years, world attention has been drawn to the acquisition by developing countries of delivery systems for nuclear weapons as distinct from the nuclear warheads themselves. In particular, concerns have been raised about the spread of ballistic-missile systems and technologies to areas such as theMiddle East, in which there are strong regional tensions.  The extensive use of ballistic missiles in the "war of the cities" in 1988 during the Iran-Iraq War and the use of Scud missiles by Iraq against Israel and Saudi Arabia during Desert Storm highlighted the rapid proliferation of these weapons, and served as a premonition of worse things to come if and when developing states deploy ballistic missiles armed with weapons of mass destruction.  The ballistic missiles of concern have ranges of a hundred to a few thousand kilometers (km) and can carry payloads of up to one or two thousand kilograms (kg). These systems are becoming increasingly prominent in Third World arsenals, and are perceived as threatening stability and regional military balances.

This study examines the impact of ballistic-missile proliferation, focusing on sixteen regional states which have or soon could have ballistic-missile capabilities.  Specifically, the study: (1) evaluates the military effectlveness of ballistic missiles in comparison with advanced strike aircraft, (2) identifies trends in the supply of and demand for ballistic missiles, (3) identifies key technologies and systems whose control is essential to a successful missile non-proliferation regime, (4) reviews the relevancy and effectiveness of present control mechanisms including the MlssiIe Technology Control Regime (MTCR), and (5) offers policy options for strengthening controls on the acquisition by developing states of longer-range ground strike delivery systems, including ballistic missiles and advanced combat aircraft.
