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.
Latin America–United States relations
Roosevelt was able to reverse a previous decision by the Walker Commission in favour of a Nicaragua Canal and pushed through the acquisition of the French Panama Canal effort. Panama was then part of Colombia, so Roosevelt opened negotiations with the Colombians to obtain the necessary permission. In early 1903, the Hay–Herrán Treaty was signed by both nations, but the Colombian Senate failed to ratify the treaty.
