What action by japan did the united states firmly oppose?

It’s expansion in Asia

Explanation:

The United States had a strong trade agreement and it was mainly responsible for supplying items such as metal, oil, etc to Japan. This is what Japan used in its war against China and United States didn’t like it.

Due to the legality of the trade agreement between Tokyo and Japan in 1911, the American government told the Japanese in 1939 of its intentions to end the trade agreement. It then stopped supplying materials to Japan due to its expansion in Asia which was a potential threat to its quest for world power also.

labor leaders and organizations had the power to demand it.

explanation:

workers got a five-day workweek because the bcea protects and respect the rights of the employees. labor leaders and other groups demanded it.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
