query: Is the Panama Canal American territory?
passage: Panama Canal Zone
In 1904, the Isthmian Canal Convention was proclaimed. In it, the Republic of Panama granted to the United States in perpetuity the use, occupation, and control of a zone of land and land under water for the construction, maintenance, operation, sanitation, and protection of the canal. From 1903 to 1979, the territory was controlled by the United States, which had purchased the land from the private and public owners, built the canal and financed its construction. The Canal Zone was abolished in 1979, as a term of the Torrijos–Carter Treaties two years earlier; the canal itself was later under joint U.S.–Panamanian control until it was fully turned over to Panama in 1999.[2]
passage: History of Panama (1977–present)
Under the provisions of Article XII, the United States and Panama agreed to study jointly the feasibility of a sea-level canal and, if deemed necessary, to negotiate terms for its construction. Payments to Panama from the commission ("a just and equitable return on the national resources which it has dedicated to the . . . canal") were set forth in Article XIII. These included a fixed annuity of US$10 million, an annual contingency payment of up to US$10 million to be paid out of any commission profits, and US$0.30 per Panama Canal net ton of cargo that passed through the canal, paid out of canal tolls. The latter figure was to be periodically adjusted for inflation and was expected to net Panama between US$40 and US$70 million annually during the life of the treaty. In addition, Article III stipulated that Panama would receive a further US$10 million annually for services (police, fire protection, street cleaning, traffic management, and garbage collection) it would provide in the canal operating areas.
