"I have been extremely concerned over the violence toward embassy activities and also toward Japanese people in China which went on for three weeks. I wish the Chinese government would sincerely handle this matter through international regulations."

The Japanese official also requested Beijing make compensations for damages to its embassy in the Chinese capital after protestors threw rocks, breaking windows in the building last weekend.

The Chinese government, while reportedly promising to penalize those responsible, stopped short of offering an official apology or compensation.

"The Japanese government has recently done a lot of things that harm the feelings of the Chinese people on issues like Taiwan and other international matters like human rights and the subject of history."

Ties between Japan and China have worsened in recent weeks, with the two countries locked in disputes involving a number of issues. Japanese history textbooks, accused of playing down Japan's World War Two aggression and a dispute over a gas field in the East China Sea are among them. And Japan has accused China of being too lenient on the protesters.

Meanwhile, the Japanese consulate in Shanghai said it would not receive direct visa applications by Chinese citizens for the time being after some demonstrators vandalized the building. Citing security concerns, the Consulate said the Chinese would have to apply for visas through travel agents.
