Modern Chinese nationalism often veers between Mr. Coubertin's and Mr. Maurras's ideas of nationhood. Officially, the government likes to talk about friendship between peoples, and harmony and peace, while at the same time promoting an injured sense of historical Chinese victimhood at the hands of foreign powers. When demonstrations of Chinese nationalism run out of control, with or without official encouragement, the feeling of national hurt can turn to violent aggression. It has been happening of late in the U.S., among other places, when Chinese students attacked Tibetans, or indeed anyone who "offended the feelings of the Chinese people."
This type of official patriotism is based on a peculiarly skewed view of history. Rather than celebrate the high points of Chinese civilization, the emphasis falls entirely on suffering at the hands of foreigners. The sense of victimhood runs so deep that it is impossible for most Chinese to view themselves as aggressors. The idea that Tibetans, for example, might have some reason to see themselves as victims of the Chinese, is absurd. More than that, many Chinese genuinely believe that this type of Tibetan "propaganda" has been deliberately taken up by the Western press to inflict yet another humiliation on the Chinese people.
Aggressive nationalism usually goes together with authoritarian politics. When people have no legitimate means to show dissent, vent their frustrations, express critical opinions in public, and generally take part in politics, nationalism fills the void. As long as they can control it, this suits authoritarian rulers. In China, a certain unspoken sense of guilt may also play a role. The same people who demanded democracy in 1989, when they were students, are now often among the fiercest nationalists. The educated urban elite has prospered since the Tiananmen Massacre, and when people are reminded of the political compromises this involved, resentment can flare up easily.
This does not mean, however, that democracy would be an automatic cure. In the unlikely event that China were suddenly to have a peaceful transformation to a liberal democracy, nationalism would not go away. No party seen to be soft on foreign powers, especially Japan and the U.S., would be. Modern Chinese history has been so bloody that the scars will take a long time to heal. Ethnic nationalism can be a kind of poison, especially when it is based on a feeling of victimhood. Political freedom should help to soothe such feelings in the long run, but this will not happen in time for the Beijing Olympics.
