United States territorial acquisitions
The Panama Canal Zone was an unorganized US territory located within the Republic of Panama. It was established under the Hay–Bunau-Varilla Treaty in 1903 and disestablished in 1979 under the Torrijos–Carter Treaties. Panama gained full control over the Panama Canal in 1999.
Title 35 of the Code of Federal Regulations
Title 35 of the Code of Federal Regulations (35 CFR) was a United States federal government regulation on the Panama Canal. The U.S. controlled the Panama Canal Zone from 1904 to 1999. The Torrijos–Carter Treaties provided for handover to Panama. After a period of joint American–Panamanian control, the canal was taken over by the Panamanian government in 1999, and is now operated by the Panama Canal Authority, a Panamanian government agency.
