"In 2008, Raúl Castro replaced Fidel as president. Cuba benefited from low-cost oil from Venezuela in exchange for thousands of Cuban health care workers and teachers. Cuba was further bolstered by the addition of Bolivia, Nicaragua, Ecuador, and other nations to ALBA. President Obama eliminated restrictions on the travel and remittances of Cuban Americans to Cuba and allowed US companies to improve the island’s telephone and Internet capabilities. Many Cubans looked forward to better relations with the US, a freer political system, and an economically improving future that would retain the best features of Cuban society. In 2013, Cuba continued its shift toward a socialist market economy and permitted its athletes, including its highly sought after baseball players, to sign professional contracts in other countries. That same year two major supporters of Cuba, Venezuela’s Hugo Chávez and South Africa’s Nelson Mandela, passed away. A historic handshake between Presidents Barack Obama and Raúl Castro at the memorial for Mandela in Johannesburg raised hopes that relations between the US and Cuba may improve."
