Wars waged by Japan against China to expand to the mainland. First Sino-Japanese War 1894-95. Under the treaty of Shimonoseki, Japan secured the `independence' of Korea, cession of Taiwan and the nearby Pescadores Islands, and the Liaodong peninsula (for a naval base). France, Germany, and Russia pressured Japan into returning the last-named, which Russia occupied 1896 to establish Port Arthur (now Luda); this led to the Russo-Japanese War 1904-05. Second Sino-Japanese War 1931-45. 1931-32 The Japanese occupied Manchuria, which they formed into the puppet state of Manchukuo. They also attacked Shanghai, and moved into NE China. 1937 Chinese leaders Chiang Kai-shek and Mao Zedong allied to fight the Japanese; war was renewed as the Japanese overran NE China and seized Shanghai and Nanjing. 1938 Japanese capture of Wuhan and Guangzhou was followed by the transfer of the Chinese capital to Chongqing; a period of stalemate followed. 1941 Japanese attack on the USA (see Pearl Harbor) led to the extension of lend-lease aid to China and US entry into war against Japan and its allies. 1944 A Japanese offensive threatened Chongqing. 1945 The Chinese received the Japanese surrender at Nanjing in Sept, after the Allies had concluded World War II.
