The tenth Review Conference of the Treaty on the non proliferation of nuclear weapons opened at the United Nations headquarters in New York on 1 August. FU Cong, director general of the Department of arms control of the Ministry of foreign affairs, led a Chinese delegation to the meeting and made a speech in the general debate of the General Assembly on 2 February, comprehensively expounding China's position on safeguarding the international nuclear disarmament and non-proliferation system based on the treaty. FU Cong said that at present, the world's century long changes and century long epidemics are intertwined, the global strategic security environment is deteriorating, and the risks of arms race and military conflict are intensifying. The international non-proliferation system based on the Treaty on the non proliferation of nuclear weapons has been seriously impacted, and even faces the most serious new challenges since the end of the cold war. China stands for taking this review conference as an opportunity to promote in a balanced manner the three pillars of the treaty, namely, nuclear disarmament, nuclear non-proliferation and the peaceful use of nuclear energy, so as to make the treaty glow with new vitality in serving peace and development. To this end, China puts forward the following three major proposals. First, adhere to the concept of common security and promote the international nuclear disarmament process. Nuclear disarmament should follow the principles of "maintaining global strategic stability" and "undiminished security of all countries". Countries with the largest nuclear arsenals should fulfill their special and priority responsibilities to further substantially and substantially reduce their nuclear arsenals in a verifiable, irreversible and legally binding manner. Nuclear weapon states should cooperate to reduce nuclear risks. Second, adhere to the direction of political settlement and address the challenge of nuclear non-proliferation. All parties should insist on pushing the comprehensive agreement on the Iranian nuclear issue back on track at an early date through diplomatic negotiations. The United States should completely lift the illegal sanctions against Iran and the "long arm jurisdiction" over the third party. On this basis, Iran should resume its commitment in the nuclear field. We should resolutely oppose "double standards" in the field of non-proliferation. The cooperation between the United States, the United Kingdom and Australia on nuclear submarines poses a serious risk of nuclear proliferation and violates the purpose and purpose of the Treaty on the non proliferation of nuclear weapons. The review conference should discuss its impact in all aspects and firmly safeguard the international nuclear non-proliferation system. It is necessary to adhere to the thinking of "dual track and simultaneous progress" and the principle of phased and simultaneous progress to promote the establishment of a peace mechanism and the denuclearization of the Korean Peninsula. The "nuclear sharing" arrangement violates the provisions of the Treaty on the non proliferation of nuclear weapons and increases the risk of nuclear proliferation and nuclear conflict. The United States should withdraw its nuclear weapons deployed in Europe and refrain from deploying nuclear weapons in other regions. Any attempt to replicate the "nuclear sharing" model in the Asia Pacific region will damage the regional strategic balance and stability, and will be resolutely opposed by countries in the region and severely countered if necessary. Third, adhere to the original intention of common development and promote the peaceful use of nuclear energy. The international community should support the IAEA in playing its central role, increase financial and technical assistance to developing countries, and fully release the potential of nuclear energy and nuclear technology. Non proliferation and peaceful use must be balanced. Under the banner of non-proliferation, some countries draw ideological lines, generalize the concept of national security, and abuse the multilateral export control mechanism. This practice must be resolutely abandoned. The peaceful use of nuclear energy should not be at the expense of the natural environment and human health. The Japanese government should seriously respond to the legitimate concerns of neighboring countries and the international community about the disposal of nuclear contaminated water in Fukushima, and fully consult with stakeholders and relevant international institutions to find proper disposal methods for nuclear contaminated water.
