A New York Times report that included 400 pages of leaked Chinese Government documents on the internment of Uyghur Muslims was "fabricated" and prompted by "hostile foreign forces", the government of the far western region of Xinjiang said.

United Nations experts and rights groups estimate more than 1 million Uyghur and members of other ethnic groups have been detained in camps in a far-reaching campaign that has triggered an international backlash.

The Times report included a series of speeches by Chinese President Xi Jinping to Xinjiang officials in 2014, as well as written directives for officials on how to speak to students whose family members had been detained.

However, it does not show Mr Xi directly ordering the creation of the detention camps.

In a statement, the Xinjiang government described the New York Times report as "fake news" that "was entirely collusion and fabrication by domestic and foreign hostile forces".

Monday's statement, released on state media, gave no details regarding which parts were fabricated.

Earlier on Monday, China's Foreign Ministry did not deny the documents' authenticity, but said the program had been successful and the "experience could be borrowed in other countries".

The documents also showed that internment camps in Xinjiang were expanded rapidly in 2016 when Chen Quanguo was appointed the Communist Party chief of the region.

China has given no official figures on the number of people detained.

Responding to the NYT report on Monday, Foreign Minister Marise Payne demanded China end the detention of Uyghurs in Xinjiang.

"The entire report is concerning," Senator Payne said.

"The over a million individuals that we have seen detailed in that [report] — that is arbitrary detention, [and] there are other restrictive measures in place.

"We very much seek the Chinese Government's amelioration of these circumstances.

"They are not observant of appropriate human rights requirements."

She declined to say whether Australia would lodge a formal complaint with the Chinese Embassy in Canberra about the matter.

The political rebuke came after The Australian newspaper revealed that China had frozen its engagement with an Australian human rights program.

The Chinese Government also blocked visas for Liberal MP Andrew Hastie and Senator James Paterson, who had been seeking to travel to the country in December.

Senator Paterson and Mr Hastie have rejected China's demands they "repent" for their criticism of the Chinese Communist Party.
