A Chinese mainland spokesperson Wednesday said Taiwan resident Lee Ming-che, who is being investigated for endangering national security, was "in good physical condition."
"Lee's medical needs have been taken care of. He has also written a letter explaining the situation clearly to his family," said Ma Xiaoguang, a mainland spokesperson with the Taiwan Affairs Office of the State Council.
"The suspect's legal rights are being protected during the investigation," he added.
Ma pointed out that the mainland has always encouraged exchanges across the Taiwan Strait. "Taiwan compatriots' rights will be protected in accordance with law as long as they are engaged in normal activities in the mainland."
