門戸開放政策
In 1902, the US government protested that the Russian incursion into Manchuria after the Boxer Rebellion was a violation of the Open Door Policy. When Japan replaced Russia in southern Manchuria after the Russo-Japanese War (1904–1905) the Japanese and American governments pledged to maintain a policy of equality in Manchuria. In 1905-1907 Japan made overtures to enlarge its sphere of influence to include Fujien. Japan was trying to obtain French loans and also avoid the Open Door Policy. Paris provided loans on condition that Japan respect the Open Door principles and not violate China’s territorial integrity.
