What role did the US after japan invasions of manchuria?

After Japan's invasion of Manchuria in 1931, the United States took several actions in response. These included:

Protesting the Japanese actions: The United States government issued a statement condemning Japan's invasion of Manchuria and called on Japan to withdraw its troops. The United States also refused to recognize the Japanese puppet state of Manchukuo, which Japan had established in Manchuria.

Imposing economic sanctions: The United States imposed a series of economic sanctions on Japan in response to its invasion of Manchuria. These sanctions included a ban on the export of arms and ammunition to Japan, as well as a ban on the import of certain Japanese goods into the United States.

Supporting China: The United States provided financial and military assistance to China in its efforts to resist the Japanese invasion. This assistance included the provision of arms and ammunition, as well as the training of Chinese troops.

Calling for a League of Nations investigation: The United States supported a League of Nations investigation into the Japanese invasion of Manchuria. The resulting Lytton Report condemned Japan's actions and called for Japan to withdraw its troops from Manchuria.

Refusing to recognize Manchukuo: The United States refused to recognize the Japanese puppet state of Manchukuo, which Japan had established in Manchuria. The United States continued to recognize the Chinese government as the legitimate government of Manchuria.

These actions by the United States demonstrated its opposition to Japan's invasion of Manchuria and its support for China. However, the United States was also reluctant to take any direct military action against Japan, and its response was limited to economic sanctions and diplomatic pressure.
