I want to know the answer to the following question:
Which countries did the Second Sino-Japanese War encompass?
All the background I'm provided with is that "Some historians contend that the conflict in Asia can be dated back to 7 July 1937 with the beginning of the Second Sino-Japanese War between the Empire of Japan and the Republic of China, or possibly 19 September 1931, beginning with the Japanese invasion of Manchuria.". Is that enough to answer the question?
Answer: yes
