China on Monday (Feb 11) pushed back against Turkish claims that a Uighur poet and musician had been tortured to death in a Chinese prison.
In the 25-second video a man identified as Heyit introduces himself and the date as February 10.
"I'm in the process of being investigated for allegedly violating the national laws", he says directly to the camera.
The criticism comes after the death of a renowned Uighur musician and poet, Abdurehim Heyit, who was in custody. "I'm now in good health and have never been abused".
Chinese foreign ministry spokesman Hua Chunying said at a briefing in Beijing that the video proved Heyit was alive.
Beijing has refuted claims of clamping down on the Uighurs, outlining that only people who have committed minor offences when involved in terrorist activities are made to go through vocational training at "vocational education institutions".
Other countries should follow Turkey's lead in calling out China's mistreatment of Uighur Muslims, said the head of a major human rights group on Sunday.
"China's systematic assimilation policy towards Uyghur Turks is a great embarrassment for humanity", the ministry said in a statement.
Roth went on to say that the "next step should be the UN Human Rights Council launching an investigation of China's outrages against Uighur and other Muslims in the Xinjiang region".
In a statement released on Saturday, Foreign Ministry spokesperson Hami Aksoy said it's "no longer a secret" that China has arbitrarily detained more than a million Uyghurs in "concentration camps".
Turks held small protests in cities nationwide to condemn China's human rights violations against Uighurs, Turkey's state-run news agency Anadolu reported on Sunday.
The northwest Xinjiang region of China, where most Uighurs live, has been under heavy police surveillance in recent years, after violent inter-ethnic tensions.
"We call on the worldwide community and the Secretary General of the United Nations to take effective measures in order to bring to an end this human tragedy in Xinjiang", Aksoy said in a statement, published on the ministry's official website late on Saturday.
