China's Defense Ministry hit back Sunday, describing the report as "presumptuous speculation".
"Our strategy will ensure Russian Federation understands that any use of nuclear weapons, however limited, is unacceptable", the document said.
The U.S. military believes its nukes are seen as too large to be used and wants to develop low-yield bombs-a move that has prompted condemnation from China, Iran and Russian Federation.
'The US Nuclear Posture Review reflects greater reliance on nukes in violation of the #NPT, bringing humankind closer to annihilation, ' Zarif said on Twitter. John Rood, Undersecretary of Defence for Policy, said: "There is no automaticity to this policy", when asked how the United States would manage responses to cases of "extreme circumstances".
The Pentagon document, known as the Nuclear Posture Review, also urged Beijing to establish "meaningful dialogue" with Washington.
A leaked version of the review, which the Pentagon is set to release soon, shows that military officials in Washington are calling for the development of a low-yield nuclear bomb that is created to be used on the battlefield instead of urban areas.

Foreign Minister Sergei Lavrov expressed "deep disappointment" at the plan. The 74-page report, the Pentagon's first since 2010, cast China as "a major challenge to United States interests in Asia". It named China, Russia, Iran and North Korea, as potential threats.
"We hope the USA will abandon a Cold War mentality and earnestly shoulder its special and prior responsibility for its own nuclear disarmament", said Ren. A year ago it said that Washington's defense strategy tied to "outdated notions".
In the NPR document, the U.S. 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 defence policy that is defensive in nature".
