Japan and representatives of former Taiwanese President Lee Teng-hui have agreed on the terms of Lee's trip to Japan, paving the way for the issuance of an entry visa, a top-ranking Japanese government official said Friday.

"We have received word from Taiwan," the official told reporters on condition of anonymity, referring to negotiations between officials at the Interchange Association, Japan's unofficial mission in Taiwan, and Lee's proxies in Taipei.

The official did not elaborate on the agreement. But separate sources said earlier that one of the conditions Japan has proposed to Lee is to refrain from conducting political activities in Japan, including meeting with Japanese politicians.
