The UN Committee Against Torture report, released yesterday, urged China to end the rampant use of torture in its prisons, close all "black jails" and halt a large-scale crackdown on lawyers and activists.
The report was not based on an "objective and fair view" of China and some contents were "based on incorrect information", said foreign ministry spokesperson Hua Chunying.
"Our position on opposing torture is firm and consistent and we believe that we will make greater efforts in this regard," she told a regular briefing in Beijing.
China's rebuttal came on International Human Rights Day, which saw both the US ambassador to China and the German embassy issue statements strongly condemning China's human rights behaviour.

"Throughout the past year, too many Chinese citizens were jailed merely for peacefully expressing their views," said US ambassador Max Baucus in a statement on the embassy website.
The statement cited several cases, including detained rights lawyer Pu Zhiqiang and Uighur economics professor Ilham Tohti who was last year convicted of separatism and jailed for life.
The embassy urged China to "adhere to its international obligations for the protection of human rights".
Hua said that accusations of human rights abuses represented "political prejudice" and a "lopsided" point of view.
"It seems that some people always choose to play up these individual cases, and they intentionally ignore the general situation of human rights in China," she said.
The United States and Germany "should not interfere in China's judicial sovereignty" when it comes to Chinese citizens and "should focus on their own domestic situations", she added.
