The correct answer is Japan’s invasion of Indochina. This happened because Indochina had strategic importance to Japan in order to protect her continental holdings. Not only this invasion facilitated Japan's operations in China but also was an important escape route for more than 600,000 Japanese troops stationed in the Netherlands East Indies.
