It signaled to those powers that the United States would take a larger role in world affairs than before.

Brief explanation: Hay’s Open Door Notes (1899–1900) urged equal trading rights in China and preservation of Chinese territorial integrity. Although they weren’t backed by force, the notes asserted U.S. interests in global affairs and led the imperial powers to accept the principle publicly, marking a more assertive U.S. role.
