BEIJING (AP) _ China said Sunday it has released Wang Dan, a leader of the 1989 Tiananmen Square pro-democracy protests, and that he has gone abroad for medical treatment.

``Chinese judicial authorities recently allowed Wang Dan to be released on bail for medical treatment in accordance with law,'' the official Xinhua News Agency said, without giving details.

Wang, 29, would be the second prominent Chinese dissident released in the past six months for medical reasons.

China has recently been encouraging dissidents to go abroad, hoping they will lose their political effectiveness. Wei Jingsheng, the leading critic of the government, was released from jail in November and sent to the United States.

Wang's parents, who say he suffers from headaches that they fear indicates he may have a brain tumor, were not immediately available for comment.

The Chinese government had denied in early April that it made a deal with Washington to release Wang after the Clinton administration refrained from criticizing Beijing's human rights record in a U.N. resolution.
