Cuba and China have signed a series of economic accords that include the expansion of an oil refinery in Cienfuegos.
Officials say the refinery agreement is a joint plan by Cuban-Venezuelan oil company Cuven Petrol SA and China's Technip Itali SA. They also plan a liquid natural gas project.
Precise details are not available. The accords were signed during a visit by Chinese Vice President Xi Jinping, who is widely expected to be the nation's next leader.
China is Cuba's No. 2 commercial partner after Venezuela.
