Japan attacked Manchuria in 1931 and China in 1937. World War II started in 1939. If the question is "As World War II progressed, Japan's desire to expand its empire led to attacks on Manchuria and China", then the answer is false because Japan invaded China before the war started.
In 1937, Japan declared war on China. Fighting continued until China officially declared war in 1941, and in doing so, also declared war on the WWII Axis. The war ended when Japan surrendered to the Allies in 1945.
