BEIJING - Japan must be responsible for the consequences should any friction take place due to its disturbance of China's normal law enforcement activities around the Diaoyu Islands, a Chinese official said Saturday.

Lyu Xinhua, spokesman for the annual session of the National Committee of the Chinese People's Political Consultative Conference, said China, as a peace-loving country, will not cause any troubles, "nor will it be afraid of any trouble-makers".

"China is willing to get along peacefully with all countries including Japan, but we have our principles and baselines," Lyu said at a press conference.

"We will never recede on issues related with China's territorial sovereignty," he said.

He urged the Japanese leaders to stop making irresponsible remarks and make substantial efforts in improving the relations between the two countries.

"Under current circumstances, what is important is that Japan must stop any activities that do harm to China's sovereignty over territory," Lyu said.
