The last treaty negotiated and signed between the United States and the Republic of Cuba was the Cuba-United States Maritime Boundary Agreement, signed on 16 December 1977, but never ratified by the United States Senate. The two governments have maintained to respect the negotiated boundaries in absence of a treaty.
The new treaty is considered to be similar to the treaty of 1977; some view it as a replacement.

Today in Washington, D.C., the United States signed a bilateral treaty with Cuba to delimit their maritime boundary in the eastern Gulf of Mexico.
The treaty delimits the only part of the U.S.-Cuba maritime boundary that had not previously been agreed, and covers an area of continental shelf in the eastern Gulf of Mexico that is more than 200 nautical miles from any country’s shore. The treaty is consistent with the longstanding U.S. goals to resolve our outstanding maritime boundaries and promote maritime safety and protection of the marine environment. Before entry into force, the treaty will warrant the advice and consent of the U.S. Senate.
