U.S. military personnel at Guantanamo Bay allegedly softened up detainees at the request of Chinese intelligence officials who had come to the island facility to interrogate the men -- or they allowed the Chinese to dole out the treatment themselves, according to claims in a new government report.

Buried in a Department of Justice report released Tuesday are new allegations about a 2002 arrangement between the United States and China, which allowed Chinese intelligence to visit Guantanamo and interrogate Chinese Uighurs held there.

According to the report by Justice Department Inspector General Glenn Fine, an FBI agent reported a detainee belonging to China's ethnic Uighur minority and a Uighur translator told him Uighur detainees were kept awake for long periods, deprived of food and forced to endure cold for hours on end, just prior to questioning by Chinese interrogators.

Susan Manning, a lawyer who represents several Uighurs still held at Guantanamo, said Tuesday the allegations are all too familiar.

U.S. personnel "are engaging in abusive tactics on behalf of the Chinese," she said Tuesday. When Uighur detainees refused to talk to Chinese interrogators in 2002, U.S. military personnel put them in solitary confinement as punishment, she said.
