BEIJING – The blind Chinese dissident who boldly fled house arrest and placed himself under the wing of U.S. diplomats balked Wednesday at a deal delicately worked out between the two countries to let him live freely in China, saying he now fears for his family’s safety unless they are all spirited abroad.

After six days holed up in the U.S. Embassy, as senior officials in Beijing and Washington tussled over his fate, Chen Guangcheng left the compound’s protective confines Wednesday for a nearby hospital for treatment of a leg injury suffered in his escape. A shaken Chen told The Associated Press from his hospital room that Chinese authorities had warned he would lose his opportunity to be reunited with his family if he stayed longer in the embassy.

U.S. officials verified that account. But they adamantly denied his contention that one American diplomat had warned him of a threat from the Chinese that his wife would be beaten to death if he did not get out of the embassy.

“I think we’d like to rest in a place outside of China,” Chen told the AP, appealing again for help from Washington.

Only hours earlier, U.S. officials said they had extracted from the Chinese government a promise that Chen would join his family and be allowed to start a new life in a university town in China, safe from the rural authorities who had abusively held him in prison and house arrest for nearly seven years.

That announcement had been timed to clear up the matter before strategic and economic meetings start today between Secretary of State Hillary Rodham Clinton, Treasury Secretary Timothy Geithner and their Chinese counterparts.
