Answer:
Both are false
Step-by-step explanation:
1. Manchuria didn't invade Japan, it was the other way around. (Unless you made a typo, then this is true.)
2. The treaty between the Axis powers was called the "Tripartite Pact" and it was not to oppose communism but rather as a defensive pact against the Allies, which did not contain the Soviet Union at this point.
