Panama Canal Zone
The Panama Canal Zone () was an unincorporated territory of the United States from 1903 to 1979, centered on the Panama Canal and surrounded by the Republic of Panama. The zone consisted of the canal and an area generally extending on each side of the centerline, excluding Panama City and Colón, which otherwise would have been partly within the limits of the Zone. Its border spanned three of Panama's provinces. When reservoirs were created to assure a steady supply of water for the locks, those lakes were included within the Zone.
Carlos Ozores
He was among the diplomats of the Panamanian delegation to the Torrijos-Carter Treaties two treaties signed by the United States and Panama in Washington, D.C., on September 7, 1977, which abrogated the Hay–Bunau-Varilla Treaty of 1903. The treaties guaranteed that Panama would gain control of the Panama Canal after 1999, ending the control of the canal that the U.S. had exercised since 1903.
