Group 1 - The U.S. has imposed punitive tariffs on countries exporting oil to Cuba, framing it as a national security threat, which effectively turns oil supply to Cuba into a high-risk business [2][3] - The U.S. strategy targets not just Cuba but also third-party countries, compelling them to choose between supplying oil to Cuba or maintaining their trade with the U.S. [2][3] - Cuba's economy is heavily reliant on external energy and foreign exchange, making it vulnerable to supply chain disruptions, particularly in electricity and food supply [2][3] Group 2 - Mexico and Venezuela are identified as key oil suppliers to Cuba, with Mexico projected to be the largest supplier by 2025 [3][4] - The U.S. aims to pressure silent oil suppliers, particularly those still providing oil to Cuba, by increasing trade costs with the U.S. [4] - Cuba's economy is primarily supported by its service sector, especially tourism, which has seen significant fluctuations due to external factors [4][6] Group 3 - Despite political tensions, economic interactions between the U.S. and Cuba persist, particularly in food imports where U.S. agricultural products play a significant role [6][8] - Cuba's short-term strategies to maintain stability include rationing and administrative mobilization, while mid-term challenges revolve around foreign exchange and fuel availability [8] - Long-term pressures on Cuba will focus on demographic and systemic resilience, with potential risks of increased emigration due to economic hardships [8]
