500 students learn Chinese at the Confucius Institute in Havana

Along with some other information from an article in Spanish here. Some of the more interesting parts:

China is the largest creditor to the island after injecting billions of dollars in loans in recent years, and is its second largest trading partner. Bilateral trade increased from $440 million in 2001 to $1.83 billion in 2010.

In keeping with the growing alliance, many Cubans are increasingly interested in learning Mandarin. The Confucius Institute in Havana, where Cuban and Chinese teachers work, has an enrollment of over 500 students, who come there since 2010 for professional reasons. Thanks to bilateral agreements, hundreds of Chinese students have also gone to Havana to learn Spanish, and others also study medicine or tourism.

China has grown in 15 years from an insignificant force in Latin America to become the largest trading partner of many countries, including Brazil. China is also a voracious consumer of raw materials in the region.
