“The country that owns the world’s largest nuclear arsenal, should take the initiative to follow the trend instead of going against it,” China’s defense ministry said on Sunday.
The US military believes its nukes are seen as too big to be used and wants to develop low-yield bombs.
Russia has already condemned the plan.
Iran’s foreign minister claimed it brought the world “closer to annihilation”.
What is the new US policy?
The US is concerned about its nuclear arsenal becoming obsolete and no longer an effective deterrent. It names China, Russia, North Korea and Iran as potential threats.
The Pentagon document released on Friday, known as the Nuclear Posture Review (NPR), argues that developing smaller nuclear weapons would challenge that assumption. Low-yield weapons with a strength of under 20 kilotons are less powerful but are still devastating. The policy also proposes:
- Land-based ballistic missiles, submarine-launched missiles, and air-delivered weapons – to be extensively modernized, as begun under ex-President Obama
- Proposed modification of some submarine-launched nuclear warheads to give a lower-yield or less powerful detonation
- Return of sea-based nuclear cruise missiles
Countering the “growing threat from revisionist powers”, such as China and Russia, was at the heart of America’s new defense strategy announced last month.
What did China say?
China said on Sunday it “firmly” opposed the Pentagon’s review of US nuclear policy.
The defense ministry in Beijing said Washington had played up the threat of China’s nuclear threat, adding that its own policy was defensive in nature.
“We hope that the United States will abandon its Cold War mentality, earnestly assume its special disarmament responsibilities, correctly understand China’s strategic intentions and objectively view China’s national defense and military build-up,” its statement said.
China has used the Cold War label before to criticize US policy. Late last year it denounced Washington’s updated defense strategy and urged the US to abandon “outdated notions”.
In the NPR document, the US accused China of “expanding its already considerable nuclear forces” but China defended its policy on Sunday saying it would “resolutely stick to peaceful development and pursue a national defense policy that is defensive in nature”.
How did others react?
The Russian foreign ministry accused the US of warmongering, and said it would take “necessary measures” to ensure Russian security.
“From first reading, the confrontational and anti-Russian character of this document leaps out at you,” it said in a statement on Saturday.
Foreign Minister Sergei Lavrov expressed “deep disappointment” at the plan.
Iranian Foreign Minister Mohammad Javad Zarif argued the proposals were in violation of the international nuclear non-proliferation treaty.
