Chinese government accuses Japan of escalating tensions between the two countries and calls it do its utmost to renew the relations between the Asian powers. Japan said that it must "seriously address and appropriately deal with its wartime historical aggression."

Last week, tens of thousands of angry Chinese took part in a violent anti-Japanese demonstrations on the streets of Beijing, Chengdu, Guangzhou and Shenzhen.

Japan has also announced its claims on China and demanded better protection to Japanese firms and emigrants.

"Japan must adopt an earnest attitude and appropriate ways to deal with major principled issues concerning the feelings of the Chinese people," said Qin Gang, the Foreign Ministry spokesman.

"The Japanese have to do more things conducive to enhancing mutual trust and maintaining the relations between the two countries, rather than doing the reverse," he added.

"I would like the Chinese side to do their utmost from now on to prevent a recurrence so this type of thing does not happen," said Japanese Prime Minister Junichiro Koizumi who also stated that Chinese anti-Japan demonstrations were "truly regrettable."

"It should do more to enhance mutual trust and safeguard the overall interests of China-Japan relations, instead of doing the contraries," said Foreign Ministry spokesman Qin Gang.
