Japan must be subject to strict oversight as it has stored excessive plutonium and is the only non-nuclear-weapon state capable of extracting weapons-grade plutonium, said a Chinese envoy at a Board of Governors meeting of the International Atomic Energy Agency (IAEA) on Friday. Li Song, China's permanent representative to the IAEA, said that Japan's recent military and security moves have raised global concerns, revealing a major negative policy shift and sending a dangerous signal to the international community. Japan, as the only country which has ever suffered atomic bombings, has upheld three principles of not possessing, producing or permitting the introduction of nuclear arms. However, Prime Minister Sanae Takaichi is considering revising the third principles. 　 Li called for caution over the new Japanese government's vague stance on the three non-nuclear principles, its discussions of "nuclear sharing" and strengthened cooperation on extended deterrence, and Japanese senior officials' claim that Japan has not ruled out the possibility of possessing nuclear submarines. If Japan wants to return to the old path of militarism, betray its commitment to peaceful development, and undermine the post-war international order, the international community will never allow it, Li said. Regarding the Fukushima nuclear disaster, Li pointed out that the Japanese government proceeded with the discharge of contaminated water into the sea in disregard of strong opposition from the international community, especially neighboring countries. China has always firmly opposed this and urged Japan to properly handle the above-mentioned issues and eliminate potential nuclear safety hazards. Hit by a 9.0-magnitude earthquake and an ensuing tsunami on March 11, 2011, the Fukushima nuclear plant suffered core meltdowns that released radiation, resulting in a level-7 nuclear accident, the highest on the International Nuclear and Radiological Event Scale.

SOUNDBITE (Chinese) Li Song, China's permanent representative to IAEA (ending with shot 3): "As we all know, Japan has long produced and stored plutonium far beyond its civilian nuclear needs. Among the members of the Treaty on the Non-Proliferation of Nuclear Weapons, Japan is the only non-nuclear-weapon state that possesses reprocessing technology, is capable of extracting weapons-grade plutonium, and still operates reprocessing facilities. A country like Japan must be subject to strict oversight."; FILE: Tokyo, Japan - Date Unknown 3. Various of Japan's National Diet building; FILE: Fukushima, Japan - Feb 6, 2024 4.
