"This open, explicit and transparent nuclear policy makes China unique among all nuclear-weapon states. China has never deployed any nuclear weapons on foreign territory," he said. "China has not participated and will not participate in any form of nuclear arms race." "China supports the early entry into force of the CTBT ( Comprehensive Test Ban Treaty) and the early commencement of the negotiation of a Fissile Material Cut-off Treaty. China will continue to keep its nuclear capabilities at the minimum level required for national security, and continue to make efforts to advance the international nuclear disarmament process," he said.
