【明報專訊】TODAY is the 86th anniversary of the Mukden Incident. And new textbooks that say the War of Resistance Against Japanese Aggression lasted fourteen years have come into use this school year on the mainland. Since the beginning of this year, signs have emerged of Sino-Japanese relations warming again. The activities to mark the 45th anniversary of the normalisation of Sino-Japanese relations Beijing saw some time ago were the first the Chinese government had held in ten years. However, Japanese Foreign Minister Kono Taro (who has just wrapped up his visit to the Middle East) is still trying to have Arab countries discussing matters concerning "maritime security". What he is doing is directed at China. And China's navy and Russia's are to have a joint military exercise in the Sea of Japan, obviously meant to be aimed at Japan. There is every indication that the basis on which Sino-Japanese relations may ease remains vulnerable, and it is probably too early to talk about the relations between them warming again.
