Havana: China is taking another great leap forward in its Latin American energy plans, raising Cuba's energy importance in the process, with a deal to lead a $6 billion (Dh22 billion) refinery expansion project on the communist island, experts said this week.

The project, to be funded mostly by China's Eximbank, is the latest of several significant moves in the region for the Asian power as it continues to expand its global influence.

For Cuba, the refurbishing of its antiquated refinery in the coastal city of Cienfuegos will provide an outlet for oil it hopes to tap soon in the Gulf of Mexico, while also laying the groundwork for the island to possibly become a key oil transhipment point for the Caribbean basin. A unit of state-owned China National Petroleum expects to begin work in early next year on the project that will more than double the refinery's capacity to 150,000 barrels daily and include construction of a liquefied natural gas terminal.

Venezuelan guarantees

Venezuela, Cuba's closest ally, will provide financial guarantees in the form of oil, a pattern followed by Beijing in other deals for energy in Latin America.

In the past two years, China has financed projects and formed joint ventures in Venezuela, Brazil and Ecuador which are expected to bring it at least 500,000 barrels of crude oil per day.

It has leased a 5 million barrel storage facility on the Caribbean island of St. Eustatius and reportedly talked with San Antonio, Texas-based refining giant Valero Energy about buying its refinery on the island of Aruba.

The Cienfuegos project is part of larger modernisation of Cuba's energy infrastructure. Brazil is financing the refurbishing and expansion of the port at Mariel, which will be the logistical platform for offshore oil operations in the Gulf of Mexico set to begin next year.
