What were the results of Japan's attack on China? How did these actions concern
Americans?

The eight-year Japanese invasion caused tremendous damage to China in terms of civilian and military casualties and property losses. More importantly, even seven decades after the end of the war, the two countries have not reached any reconciliation.The United States responded to this growing threat by temporarily halting negotiations with Japanese diplomats, instituting a full embargo on exports to Japan, freezing Japanese assets in U.S. banks, and sending supplies into China along the Burma Road.
