Question

why was theodore roosevelt worried about japan winning the russo - japanese war? (1 point)
○ russia supported unlimited u.s. access to chinese markets.
○ japanese victory could limit american access to chinese markets.
○ the u.s. had agreed to support japan in any war with european nations.
○ a treaty with russia required the u.s. to provide supplies to it during any war.

Explanation:

Theodore Roosevelt was concerned about the balance of power in East Asia. At that time, the U.S. had an interest in maintaining an "open door" policy in China, which meant equal access for all countries to Chinese markets. If Japan won the Russo - Japanese War, it might gain more influence in East Asia. This could potentially lead to Japan restricting American access to Chinese markets, as Japan might seek to create its own sphere of influence. Russia, on the other hand, was not a strong supporter of unlimited U.S. access (so the first option is wrong). There was no such treaty as described in the third and fourth options that would make Roosevelt worry in the context of the Russo - Japanese War.

Answer:

Japanese victory could limit American access to Chinese markets.
