Why did Colombia reject the canal treaty with US in 1903?

Colombia rejected the canal treaty with the United States in 1903 primarily due to concerns over national sovereignty and the financial terms of the agreement. The Colombian government felt that the treaty favored U.S. interests disproportionately and did not provide sufficient compensation for the land needed for the canal. Additionally, there was a strong nationalistic sentiment against foreign intervention in Colombian affairs, which contributed to the rejection of the treaty. This decision ultimately led to U.S. support for Panama's independence and the eventual construction of the canal.
