Abstract: After the cold war, China's peripheral nuclear situation has become complex, with nuclear proliferation in the region around China pursuing two opposite directions. On the one hand, in the Northeast Asian region, North Korea's nuclear provocations have triggered a serious nuclear crisis; and in the South Asian region, India and Pakistan have crossed the nuclear threshold to become nuclear nations. On the other hand, many other countries and areas around China have accelerated their effort at denuclearization or non-nuclearization, such as Southeast Asia, Mongolia and Central Asia, have announced the establishment of a nuclear-free-zone, which has helped to stabilize the security situation in this region and consolidate the international nuclear nonproliferation mechanism. The two different nuclear trends, in certain areas around China in this postcold war era, are the result of the interaction and mutual influence of various factors, which include international security environment, regional security environment, and domestic politics in certain key countries.

Key words: the region around China , the nuclear situation , nuclear proliferation , the nuclear-free zone
