Kurt M. Campbell, an assistant secretary of state, quietly arrived in Beijing on 29 April for negotiations with representatives of China's Ministry of Foreign Affairs. After several days of media speculation as to his whereabouts, Chen was confirmed on 2 May to have been under U.S diplomatic protection at the Embassy. According to embassy representatives, the agreement brokered with Chinese authorities provided that Chen would be freed from soft detention, relocated, and be permitted to finish his legal education at one of several law schools in China. Chinese officials also promised to investigate "extra-legal activities" taken by Shandong province authorities against Chen and his family. Chen left the embassy of his own accord on 2 May, was reunited with his family, and admitted to Beijing's Chaoyang Hospital for medical treatment.
