China says it firmly opposes the Pentagon's Nuclear Posture Review. The US Department of Defense report released Friday accused China of building up nuclear capabilities with little transparency.

Chinese Defense Ministry spokesman Ren Guoqiang said that China will resolutely stick to peaceful development and pursue a national defense policy that is defensive in nature. China adheres to the policy of "no first use" of nuclear weapons at any time and under any circumstances. Ren also urged the US, which possesses the world's largest nuclear weapons arsenal, to shoulder its responsibility for nuclear disarmament and to discard its "Cold War" mentality.
