Question

what effect did john hays open door policy letters have on the imperial powers of britain, france, germany, russia, and japan? it provoked the imperial powers to declare war on the united states, it caused the imperial powers to restrict trade in their trade with china, it warned the imperial powers that the united states would soon declare war on china

Answer 1

None of the three choices is correct.

John Hay’s “Open Door” notes (1899–1900) did not provoke war, did not trigger trade restrictions, and were not a warning that the United States would declare war on China. Instead, Hay’s letters asked the imperial powers to guarantee equal commercial access to China and to respect China’s territorial and administrative integrity — a diplomatic assertion of U.S. policy rather than a threat. The responses from Britain, France, Germany, Russia and Japan were mostly vague or noncommittal, but none openly rejected the idea or went to war with the U.S. The practical effect was limited at first, but the notes helped establish the principle of open access that the U.S. would invoke diplomatically (especially after the Boxer Rebellion) and discouraged formal partition of China.
