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
The Panama Canal, the area supporting the Canal, and remaining US military bases were turned over to Panama on December 31, 1999 in accordance with the Torrijos-Carter Treaties.
