China rejects Trump claim it is secretly testing nuclear weapons

China on Monday dismissed a claim by U.S. President Donald Trump that Beijing is secretly testing nuclear weapons, saying it remains committed to a self-defensive nuclear strategy and its pledge to halt nuclear testing.

As a permanent member of the United Nations Security Council and a responsible nuclear-weapon state, China upholds its no-first-use nuclear weapons policy and firmly supports the authority of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), Foreign Ministry spokesperson Mao Ning told media at a regular press briefing.

Mao expressed hope that the U.S. will also strictly honor its obligations under the CTBT and maintain its own moratorium on nuclear testing, and will take concrete actions to uphold the international nuclear disarmament and non-proliferation regime.
