China has made "impressive progress" in developing new nuclear weapons, but will only use them for self-defence, and never use them first, Chinese Defence Minister Wei Fenghe told delegates at the Shangri-La Dialogue on Sunday.
In response to a question about reports last year on construction of more than 100 new nuclear missile silos in China's east, he said China "has always pursued an appropriate path to developing nuclear capabilities for protection of our country".
