Cotton On and Target have stopped buying cotton from China's Xinjiang province where persecuted Muslims are forced to work in factories.

The Chinese state has detained up to one million Uighur muslims since 2014 under the guise of cracking down on domestic terrorism.

Many are held in camps or forced to work in textile factories and cotton mills, according to eyewitness reports.

The ABC's Four Corners in July revealed that Cotton On and Target were reviewing their cotton supply chains due to fears of human rights abuse.

Now the current affairs programme has reported that both retail giants have cut ties with Xinjiang.

Cotton On used to source its cotton from Litai Textiles which had a factory near a camp where persecuted Muslims are held.

On Thursday it said it has changed supplier and is 'absolutely committed to having an ethical supply chain'.

Target Australia used to source cotton from a mill owned by the Huafu company but no longer does after sending employees to investigate.

A spokesman said the store has 'made the decision to stop orders from that mill.'

Daily Mail Australia has contacted Cotton On and Target for further comment.

UN experts and activists say at least one million ethnic Uighurs and other Muslims are held in the detention centres in Xinjiang.

China describes them as 'training centres' helping to stamp out extremism and give people new skills.

Former detainees have revealed that Muslims were forced to eat pork and speak Mandarin in those internment camps.

China has also kept thousands of Uighur children away from their Muslim parents before indoctrinating them in camps posing as schools and orphanages.

Last week US Secretary of State Mike Pompeo compared the program to George Orwell's dystopian novel 1984 which depicts repressive, overreaching government.

Speaking at an American Association of Christian Counselors event in Nashville, Tennessee, he said: 'The Chinese Communist Party is detaining and abusing more than one million Uighur Muslims in internment camps in Xinjiang, the western region of China.

Authorities in China's Xinjiang region have rounded up an estimated one million mostly Muslim Turkic-speaking minorities into internment camps in what they call an 'anti-terror' campaign

A Western intelligence official was able to verify the movement of some 500 prisoners earlier this year from Kashgar to Korla in Xinjiang, a Muslim-dominant region in western China

'The pages of George Orwell's 1984 are coming to life there.'

It comes after shocking footage emerged which was believed to show hundreds of shackled and blindfolded Muslim prisoners being transferred.

The drone video, believed to be taken in Xinjiang in western China, shows the detainees being led from trains with their heads shaven, eyes covered and hands bound.

The alleged prisoners are also seen in the clip sitting in rows outside what appears to be a train station watched by dozens of SWAT officers.

Many of them, thought to be ethnic minority Uighurs, are seen wearing purple vests with the words 'Kashgar Detention Center' written on their backs.

US officials believed the footage to be authentic.
