Protesters hold signs reading "Japan get out of Diaoyu islands" during an anti-Japan protest over disputed islands called Diaoyu in China and Senkaku in Japan, outside the Japanese embassy in Beijing September 18, 2010, on the 79th anniversary of September 18 Incident of 1931. About a hundred Chinese protesters on Saturday demanded Japan free a Chinese boat captain, but tight security and rain deterred a bigger show of anger over an issue that has ratcheted up territorial tensions between the Asian powers. Japan on September 18, 1931 laid siege to Mukden (now Shenyang) and began the military occupation of northeast China, then known as Manchuria, an act of aggression that marked the beginning of the Sino- Japanese War.
