The State Department said this week it is investigating reports that Kennedy School of Government graduate and pro-democracy activist Yang Jianli has been physically abused in the Beijing prison where he has been held for almost two years.

Yang was moved last month to solitary confinement where he was handcuffed, prevented from exercising and denied access to reading materials and his lawyer, according to his wife, Harvard Medical School researcher Christina X. Fu.

The handcuffs were not removed until Yang’s hands were bloody and infected, Fu said. Mo Shaoping, Yang’s lawyer, said his client’s hands were still bruised and swollen when he visited him in prison last week.

The State Department said it is investigating the allegations of abuse and trying to secure Yang’s release.

“We are seeking further information about his situation,” said State Department spokesperson Jeffrey M. Jamison.

“We continue to communicate our concerns to the Chinese and urge them to release Dr. Yang.”

But efforts on behalf of Yang have been complicated by a recent breakdown in human rights dialogue between China and the United States.

China suspended official communications after the United States introduced a resolution at the U.N. Human Rights Commission last month criticizing China’s human rights record. The commission decided not to approve the resolution.

“The Chinese side cannot but immediately halt bilateral human rights dialogue and exchanges,” Chinese Assistant Foreign Minister Shen Guofang said last month.

Jamison said the United States will continue to press for Yang’s release through informal channels.

“This is a message we will continue to convey in meetings with the Chinese, whether or not the formal U.S.-China Human Rights Dialogue resumes,” he said.

The Chinese Embassy declined to comment yesterday about Yang.

The allegations of abuse come almost two years after Yang’s arrest in Kunming for entering the country using false identificationon on April 26, 2002. He had been banned from China following his involvement in the 1989 pro-democracy protests in Tiananmen Square.

Yang was tried in Chinese court last August on charges of espionage and visa violations. A verdict was supposed to be issued by December.

But more than eight months after the trial, a verdict has not been issued—in violation of Chinese law, according to Fu.
