Calls for Beijing to take part in eventual Russia-U.S. nuclear disarmament talks are unrealistic, Chinese Foreign Ministry spokesman Guo Jiakun told reporters at the Foreign Ministry briefing today. “The country sitting on the world’s biggest nuclear arsenal should earnestly fulfill its special and primary responsibility for nuclear disarmament, further make drastic and substantive cuts to its nuclear arsenal, and create conditions for the ultimate realization of complete and thorough nuclear disarmament,” Guo said. “China’s nuclear strength is by no means on the same level with that of the U.S. Our nuclear policy and strategic security environment are also completely different. It’s neither reasonable nor realistic to ask China to join the nuclear disarmament negotiations with the U.S. and Russia.
