It then tried to occupy China and that resulted in the Sino-Japanese war. France, British, and the U.S. were supplying goods to China during the war.
Japan's main goal was to capture Singapore. Also, it had plans on occupying Malay which was under British control. America asked to Japan to withdraw its conquest idea.
