Which policy lead world leaders of the early 1900s to carve up China?

The policy that led world leaders to carve up China in the early 1900s was known as the "Open Door Policy." Initiated by the United States in 1899, this policy aimed to ensure equal trading rights for all nations and prevent any single power from monopolizing trade with China. This, combined with China's internal struggles and the weakening Qing Dynasty, prompted various foreign powers to establish spheres of influence within China, effectively dividing the country among themselves. As a result, China faced significant foreign intervention and loss of sovereignty.
