|The First 'Open Door Note'
United States Department of State
Washington, September 6, 1899
At the time when the Government of the United States was informed by that of Germany that it had leased from His Majesty the Emperor of China the port of Kiao-chao and the adjacent territory in the province of Shantung, assurances were given to the ambassador of the United States at Berlin by the Imperial German minister for foreign affairs that the rights and privileges insured by treaties with China to citizens of the United States would not thereby suffer or be in anywise impaired within the area over which Germany had thus obtained control.
More recently, however, the British Government recognized by a formal agreement with Germany the exclusive right of the latter country to enjoy in said leased area and the contiguous "sphere of influence or interest" certain privileges, more especially those relating to railroads and mining enterprises; but as the exact nature and extent of the rights thus recognized have not been clearly defined, it is possible that serious conflicts of interest may at any time arise not only between British and German subjects within said area, but that the interests of our citizens may also be jeopardized thereby.
