China has accused the US of a 'Cold War' mentality after Washington's decision to expand its nuclear capability.
The US decision to expand its nuclear capacity has been slammed by China which has urged Washington to drop its Cold War mentality.
China says it is "firmly" opposed the Pentagon's review of nuclear policy. The defence ministry in Beijing said the US had played up the threat of China's nuclear threat, adding that its own policy was defensive in nature.
The US is concerned about its nuclear arsenal becoming obsolete and no longer an effective deterrent and names China, Russia, North Korea and Iran as potential threats.
Iran says the move is in violation of the international nuclear non-proliferation treaty and claims it has brought the world closer to annihilation.
Russia was also quick to react accusing the US of warmongering. Moscow said it would take "necessary measures" to ensure Russian security.
