China made notable strides to join formal arms control regimes in the 1990s—beginning with its accession to the NPT in 1992, its signature in 1993 and ratification in 1997 of the Chemical Weapons Convention (CWC), and its cessation of nuclear weapon explosive testing and signature of the Comprehensive Test Ban Treaty (CTBT) in September, 1996. China has supported the multilateral negotiations on a fissile-material production cutoff convention. China also acceded to the Biological Weapons Convention (BWC) in 1984. Moreover, China has gradually clarified and upgraded the commitments it makes through export controls to nuclear and missile non-proliferation objectives. These nuclear export control clarifications and practical improvements are worthy of note, as are the areas of continued divergence.
China is still on a learning curve, and endemic problems of a political, cultural, and organizational nature exist in China’s decision-making and export control apparatus. There may be, as the old adage goes, "more than a slip between the cup and the lip." Thus, continued vigilance and diplomatic interchange with China will certainly be necessary on nuclear matters. China is not a member of the Nuclear Suppliers Group, which requires a recipient country to have full-scope IAEA safeguards before receiving nuclear assistance from a member country. China is, however, a member of the Zangger Committee, which only requires site-specific safeguards of the nuclear complex assisted. This has enabled China to help Pakistan with the Chasma nuclear power plant, that was recently commissioned.
The missile, chemical and biological areas will also require diligent attention. Up to 1994, China made progress on MTCR requirements. But it is still not clear that its professed restraint applies, as the MTCR requires, to missile components and technology—nor, indeed, that the restraint applies to more than complete "ground-to-ground" missiles. Compliance in this area, which is not defined by a treaty, is harder to nail down with standards that China can accept politically—and also entails more scope for ambiguities. In February 2001 the CIA reported to Congress that China continued to provide substantial support to Pakistan’s missile programs. The chemical area is defined by treaty, provides for declarations, and lists restricted items, but it covers a very large industrial domain.
