the panama canal
The Panama Canal is owned today by China. We know the Panama Canal's ownership caused many problems in the past and a treaty was signed in 1977 between the U.S. and Panama. At the end of 1999 however, it was handed over to China.
The Panama Canal.
The United States, under president Teddy Roosevelt built the Panama Canal.

The US controlled the Panama Canal Zone directly from 1903 until the exclusive US-led government was abolished on October 1, 1979, as a term of the Torrijos–Carter Treaties of 1977. From 1979 until December 31, 1999٫ the canal itself was under joint U.S.–Panamanian control. It was on DECEMBER 31, 1999 that full control of the canal was restored to Panama.
The King of Spain Charles V was the first person to order the conduct of feasibility of building a canal in Panama. His interest was to find a way that would reduce the travelling time between Spain and Peru.
The U.S. Army was stationed at the Panama Canal from its construction in the early 1900s until the end of U.S. control over the canal in 1999. The construction officially began in 1904 and was completed in 1914, with a military presence maintained throughout the years. The U.S. military presence was formalized under the Hay-Bunau-Varilla Treaty, and it continued until the Panama Canal Treaty of 1977 established a timeline for the eventual transfer of control to Panama by December 31, 1999.
The United States, particularly under President Theodore Roosevelt, subtly encouraged Panama's independence from Colombia in 1903 to facilitate the construction of the Panama Canal. The U.S. government supported a revolution in Panama, believing that an independent Panama would be more amenable to granting the necessary lease for the canal. After Panama declared independence, the U.S. quickly recognized the new government and secured the Hay-Bunau-Varilla Treaty, which granted the U.S. control over the canal zone.
YesThe canal and the surrounding area has legally been considered Panamanian since December 31st 1999. Before then it was under US control and used primarily as a military base. Former presidential Candidate John McCain was born in the canal zone while it was under US control, and was allowed to run for president in the 2008 election because it was counted as the United States for all legal purposes (though it was not a state).
When the U.S. transferred control of the Panama Canal to Panama in 1999, it retained the right to intervene in the canal's operations to ensure its neutrality and security. This was established under the Torrijos-Carter Treaties of 1977, which aimed to ensure that the canal would remain open and accessible to all nations for peaceful navigation. Additionally, the U.S. retained the right to protect its interests and the security of the canal zone until the transfer was completed.
