BEIJING (Reuters) -China had no comment on a think tank's report about nuclear weapons which said China had the fastest-growing nuclear arsenals, a spokesperson for the country's foreign ministry said on Monday. China has always adhered to the strategy of self defence, maintained its nuclear force at the minimum level required for national security, and does not participate in an arms race, spokesperson Guo Jiakun said at a regular press conference.
