I want to know the answer to the following question:
When did Japan invade China?
All the background I'm provided with is that "It is generally considered that the Pacific War began on 7/8 December 1941, on which date Japan invaded Thailand and attacked the British possessions of Malaya, Singapore, and Hong Kong as well as the United States military bases in Hawaii, Wake Island, Guam and the Philippines.". Is that enough to answer the question?
