There have been anti-Japanese demonstrations and riots as recently as today in Shanghai, Zhuhai, Dongguan, and other locations. The Chinese and Japanese foreign ministers met at Beijing. The Japanese foreign minister solicited an apology for damage to Japanese-owned businesses. The Chinese foreign minister declared that no apology will be forthcoming. "China rejects Japan's demand for apology" http://www.cbc.ca/storyview/MSN/world/national/2005/04/17/china-japan050417.html Some principal points of contention. 1. The Japanese Ministry of Education has come out with a line of textbooks which, Chinese critics say, short-shrift Japanese atrocities that were an aspect of the Japanese invasion of China. 2. Chinese resent Japan's bid to obtain permanent membership in the U.N. Security Council. 3. China has, in recent years, become a net oil importer. Proponents of the "Peak Oil" hypothesis assert that global oil production has peaked and will decline hereafter. I have read that China views with particular annoyance commencement of offshore geophysical drilling for natural gas by the Japanese in waters as to which China claims priority. 4. I have read expressions of anger by Japanese authorities over the policy of the Chinese central bank of pegging the renminbi to the U.S. dollar. Every time the dollar declines in the foreign exchange market (which has been the trend for about the last three years), Chinese goods become cheaper (in local currency terms) in markets in which Chinese and Japanese sellers compete. 5. Japan may be making its first tentative moves in the direction of rearmament.
