What was the effect of America's withdrawal from a 30-year trade agreement with Japan?

Japan and the United States had relatively good trade relations at the beginning of the 20th century. However, the involving of Japan in the Second Sino-Japanese War in 1930 meant the withdrawal of the United States of their current trade agreement and a further imposition of economic sanctions. This led to tense relations between both countries that escalated into an all-out war on December 1941, with the bombing of Pearl Harbor by the Japanese.
