Panama Canal
Colombia, France, and later the United States controlled the territory surrounding the canal during construction. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for handover to Panama. After a period of joint American–Panamanian control, in 1999, the canal was taken over by the Panamanian government. It is now managed and operated by the government-owned Panama Canal Authority.
History of Panama (1977–present)
On September 7, 1977, Carter and Torrijos met in Washington to sign the treaties in a ceremony that also was attended by representatives of twenty-six other nations of the Western Hemisphere. The Panama Canal Treaty, the major document signed on September 7, abrogated the 1903 treaty and all other previous bilateral agreements concerning the canal. The treaty was to enter into force six months after the exchange of instruments of ratification and to expire at noon on December 31, 1999. The Panama Canal Company and the Canal Zone government would cease to operate and Panama would assume complete legal jurisdiction over the former Canal Zone immediately, although the United States would retain jurisdiction over its citizens during a thirty-month transition period. Panama would grant the United States rights to operate, maintain, and manage the canal through a new United States government agency, the Panama Canal Commission. The commission would be supervised by a board of five members from the United States and four from Panama; the ratio was fixed for the duration of the treaty. The commission would have a United States administrator and Panamanian deputy administrator until January 1, 1990, when the nationalities of these two positions would be reversed. Panamanian nationals would constitute a growing number of commission employees in preparation for their assumption of full responsibility in 2000. Another binational body, the Panama Canal Consultative Committee, was created to advise the respective governments on policy matters affecting the canal's operation.
