China is "strongly dissatisfied" with Japan for its allowing Lee Teng-hui's entry into the country, and the Foreign Ministry has lodged strong protest to the Japanese government over the issue, said Chinese Foreign Ministry spokesman Liu Jianchao Monday.

The Japanese government insisted on allowing Lee to enter the country despite China's repeated representations and firm protest, Liu said. He called it a "wrong decision."

He said Lee is the chief representative of the radical force for Taiwan independence on Taiwan Island and is "an out-and-out trouble maker in the international arena."

Liu said by allowing Lee's entry into Japan the Japanese government is conniving with and supporting the Taiwan independence force. The move has sent a "wrong signal" to the Taiwan independence force, and has "severely disturbed" the political foundation of China-Japan relations.

China has "seriously requested" the Japanese side to value the overall situation of China-Japan relations, and take effective measures to "remove the bad influence of the issue," Liu said.

He said China will closely follow the development of Lee's visit, and reserve its right to make further reaction.
