What are the Caribbean countries that took part in the London Olympics 2012?

Answer 1

There were many and it's hard to make a decision who to include. Some continental countries also have islands in the Caribbean, including Colombia (which has 10 islands in the Caribbean Sea, known as San Andrés-and-Providencia), Mexico (4 islands), Nicaragua (4), Venezuela (15), Belize, Guatemala, Honduras, Costa Rica and Panama. The United States also claims several small Caribbean islands (including Alto Velo).
