The Cox Commission of the U.S. Congress was established in June 1998 to investigate concerns over Chinese acquisition of sensitive U.S. missile and space technology in connection with the launching of U.S. civilian satellites using Chinese launchers on Chinese territory. The investigations were broadened in October 1998 to include alleged security problems and possible espionage at the U.S. nuclear weapons laboratories. Some conclusions were released in January 1999 by the White House together with the administration's response. The full declassified (redacted) version of the report of the Cox Commission was released on May 25, 1999.

The U.S. Senate's rejection of the CTBT in October 1999 does not free the United States from the Treaty's norm against nuclear-weapon test explosions. Nor does it mean that the Senate will never approve the Treaty. But it does mean that the final U.S. position on the Treaty almost certainly will not be known until after the next U.S. presidential election in November 2000. Moreover, a debate to build domestic and international support for U.S. adherence to the Treaty's norm could help to produce eventual Senate approval.

The nuclear nonproliferation regime was challenged in 1998 by nuclear-weapon tests in India and Pakistan, by medium-range missile tests in those countries and in Iran and North Korea, by Iraq's defiance of UN Security Council resolutions requiring it to complete its disclosure of efforts to acquire weapons of mass destruction, and by the combination of "loose nukes" and economic collapse in Russia. Additional threats to the regime's vitality came in 1999 from the erosion of American relations with both China and Russia that resulted from NATO's 1999 bombing of Yugoslavia--with additional harm to relations with China resulting from U.S. accusations of Chinese nuclear espionage and Taiwan's announcement that it was a state separate from China despite its earlier acceptance of a U.S.-Chinese "one China" agreement. Major threats to the regime also came from the continued stalemate on arms-control treaties in the Russian Duma and the U.S. Senate, from a change in U.S. policy to favor building a national defense against missile attack, and from a Russian decision to develop a new generation of small tactical nuclear weapons for defense against conventional attack.

This paper will discuss the effect some of these developments had on the 1999 Preparatory Committee (PrepCom) meeting of Non-Proliferation Treaty (NPT) parties to prepare for review of the NPT in 2000, and speculate about their likely future effect on the regime.

Can the current global moratorium on nuclear weapon testing survive the May 1998 tests by India and Pakistan and the refusal of US Senate leaders to permit consideration of the Comprehensive Test Ban treaty (CTBT) by the Senate? If nuclear testing resumes by India or Pakistan - or by Britain, China, France, Russia, or the United States - will it be condemned by most of the world as if an international norm against testing was already in effect? What will be the likely consequences for nonproliferation if tests resume? This article seeks to show that there are norms operating against nuclear testing even though the CTBT has not been ratified, and that renewal of testing would have widespread consequences.

In the 1990s, global concern over illicit trafficking in nuclear material to terrorists and nation-states has intensified. Two major changes are responsible: the evident new intent of terrorists to wound or kill thousands of civilians and the availability of inadequately protected "loose" nuclear materials in Russia and the newly independent former Soviet republics. These changes have made more likely attempts to acquire weapons-usable nuclear materials for terrorist use or for sale to state sponsors of terrorism. As a result, many efforts are being made to strengthen national and international standards for protection of nuclear material from theft and sabotage. One problem with current efforts is that national stnadards now vary widely. Although the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) mandates that non-nuclear weapon parties accept the safeguards requirements of the International Atomic Energy Agency (IAEA) for their nuclear activities, the relevant international standards for physical protection are mostly advisory.

There is a growing logjam of arms control treaties waiting for approval in both the Russian State Duma and the U.S. Senate. Without decisive action, this logjam will probably prevent approval by the world's two largest military powers of the Strategic Arms Reduction Treaty (START II) of 1993, the Comprehensive Test Ban Treaty of 1996 (CTBT), amendments to the Anti-Ballistic Missile (ABM) Treaty, and the protocols of the Treaty of Pelindaba (creating an African nuclear-weapon-free zone (NWFZ)) and the Treaty of Rarotonga (creating a South Pacific NWFZ) before the end of the century. It will also prevent progress towards START III and further bilateral nuclear reductions.

This paper focuses on the impact of a comprehensive test ban on China's nuclear program and security policy. After a general review of China's nuclear doctrine and development, the study analyzes the relationship between China's nuclear strategy and its desire for testing, and explores the reasons China decided to join the Comprehensive Test Ban Treaty. By comparing the maturity of the nuclear programs of the nuclear states and the degree of their preparations for a cessation of nuclear tests, this paper concludes that a comprehensive test ban would place greater constraints on China's nuclear program than on those of the others. Efforts such as a deeper reduction of the nuclear arsenals of the principal nuclear powers, a no-first-use commitment by all nuclear states, and the adherence to the ABM treaty by its signatories would be critical to reducing China's concerns. The progress of international arms control negotiations in the above directions would further encourage China to make even greater contributions in the field of global arms control in the post-comprehensive test ban era.

This volume contains the proceedings of a conference held at the Center for International Security and Arms Control in May 1996. The meeting was the latest in a series that CISAC had held over the years with Russian specialists from the Center for Scientific Research of the Committee of Scientists for Global Security, the Ministry of Defense, and the Russian Academy of Sciences. The general rubric under which these meetings were organized is "Strategic Stability to the Year 2000."

The May meeting had a special significance because 1996 was a year of presidential elections in both Russia and the United States, and the prospect of these elections was inevitably reflected in the discussions. But another general point emerged in the meeting, and that was the need to pay more attention to the strategic relationship between Russia and the U.S. Much had been done since the end of the Cold War to wind down the nuclear competition between the two countries, and agreements have been signed to reduce the enormous nuclear arsenals built up during the Cold War. There is much to be done, however, to ensure that this course is continued. The uncertainty
about ratification of START II by the State Duma, and the proposals in the U.S. Congress for deployment of a national ABM system both cast doubt on the possibility of further reductions in strategic offensive arms. The prospects for pushing nuclear weapons into the background of international politics are clouded by the renewed Russian interest in the role of tactical weapons in regional conflicts, and by U.S. interest
in the use of nuclear weapons to deter chemical and biological weapons attacks.

The issues discussed in the conference are embedded in broader political relationships, and this meeting suggested the need for a more intensive and broader strategic dialogue. In both countries there had been a lessening of interest in issues of arms control, but the process of reducing and eliminating nuclear weapons, to which both states are formally committed, is a complex and contentious one, which requires
political trust and careful management. Hence, the importance of a strategic dialogue which examines the conceptual basis of Russian-U.S. relations. Several participants in the conference spoke of the need to transform, or move away from, nuclear deterrence.
Many proposals were advanced for further cooperation in arms control and disarmament. But it is clear that much remains to be done to move Russian-U.S. relations onto a more stable footing.

This article analyses whether the Nuclear Non-Proliferation Treaty (NPT) provides legal authority for International Atomic Energy Agency (IAEA) efforts to gain more information and more intrusive inspections to assure that non-nuclear-weapons States (NNWS) have joined the NPT are not attempting to make nuclear weapons in violation of that Treaty.
