How did Americas open door policy clash with Europes spheres of influence?

America's Open Door Policy, established in the late 19th and early 20th centuries, aimed to ensure equal trading rights for all nations in China, opposing exclusive spheres of influence held by European powers. This policy conflicted with Europe's interests, as countries like Britain, France, and Germany sought to expand their control over Chinese markets and resources. The U.S. push for open access challenged European dominance and aimed to prevent any single power from monopolizing trade in China, leading to tensions between the U.S. and European nations. Ultimately, the Open Door Policy reflected America's desire for economic expansion while undermining European colonial ambitions.
