China's national soccer team lost by a score of 3 to 1 to the Japanese team in the Asian Cup final in Beijing on Aug. 7. For the increasing number of ultra-nationalistic Chinese, losing the championship at home to the hated Japanese was simply unbearable.
During the game, Chinese fans shouted -- among other insulting chants -- "Kill! Kill! Kill!" After the game, they burned Japanese flags, pelted the Japanese team bus with bottles, and pounded a limousine carrying a Japanese embassy official.
The bitter collective memory of Japan's invasion of China and the brutality of its soldiers during the war certainly has contributed to a prolonged anti-Japanese sentiment over the years. The unwillingness of the Japanese government to "sincerely apologize" for the wrong the Japanese did to China has not helped either.
