August 30, 2006: Despite irritation at Japanese prime minister Junichiro Koizumi's tactless visits to the Yakasuni Shrine (where World War II war criminals are honored), the Chinese are sending signals that they'd like an improved security relationship. Apparently the Chinese have been letting drop hints about possible mutual port calls by warships, and perhaps exchange visits by military personnel, to talk shop. The Japanese believe the primary reason for this possible easing of China's generally hostile line, is concern over the increasing problem posed by North Korea. The Chinese might also be trying to woo the Japanese away from close ties with Taiwan.
