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.
Panama Canal
At this time, the President and the Senate of the United States were interested in establishing a canal across the isthmus, with some favoring a canal across Nicaragua and others advocating the purchase of the French interests in Panama. Bunau-Varilla, who was seeking American involvement, asked for $100 million, but accepted $40 million in the face of the Nicaraguan option. In June 1902, the US Senate voted in favor of the Spooner Act, to pursue the Panamanian option, provided the necessary rights could be obtained.
