Secretary of State John Kerry says that while the United States welcomes changes taking place in Cuba that allow Cubans to travel more freely and work for themselves, Havana needs to do more.
Speaking on Monday to the Organization of American States in Washington, Kerry said that despite the recent changes, Cubans still live under an authoritarian government, cannot freely choose their leaders or criticize their leaders without fear of arrest or violence.
Kerry says that if more does not change soon, the 21st century will leave the Cuban people behind.
Kerry also said again that Latin American leaders have "understandable concerns" about National Security Agency leaker Edward Snowden's recent disclosures about widespread surveillance in countries, including Brazil and Mexico.
