South Koreans seem to be quite supportive of China’s anti-Japanese demonstrations. But then experience of Japanese colonialism is something that China and Korea have in common. That’s also true for Malaysia and Indonesia; not to mention the Philippines and Vietnam, where a couple of million people died of starvation under Japanese rule. Mongolia and Taiwan have highly conflicted histories with Japan. The current Taiwanese government represents the KMT version of the Chinese anti-Japanese tendency: in Mongolia, you have the fact that the Bloody White Baron was historically a major agent of Japanese influence.
What I’m wondering here is if a revival of a pan-Asian, anti-Japanese sensibility may actually be part of the wider plan here, something to counter the containing alliance/offshore balancing configuration the US wants to set up against China, and something which mitigates all the other maritime disputes going on right now. So if China’s response to Japan’s nationalization of the disputed territories leads to a more aggressive Japanese stance on territorial issues, past victims of Japanese aggression respond by leaning towards China. At any rate, it’s worth remembering that anti-Japanese sentiment has real historical causes and isn’t confined to Chinese fenqing.
