There has been a second day of anti-Japanese protests in China.

The demonstrators are angry at new Japanese school textbooks which they say play down Japan's wartime atrocities, such as the mass sex slavery of Asian women by Japanese troops.

Some 3,000 people gathered outside Japan's consulate in the southern city of Guangzhou, a day after similar protests in the capital, Beijing.

Chinese authorities appealed for calm after the demonstrators in Beijing attacked the Japanese embassy and smashed windows of Japanese-owned businesses.

Japan's Foreign Minister Nobutaka Machimura has announced he will visit China next week.

Japan has issued a formal complaint and has summoned China's Ambassador to Tokyo, Wang Yi.
