Economy

The economy of Trinidad and Tobago is diversified, based to a large extent on oil and natural gas. It is one of the leading gas-based export centers in the world, being one of the top five exporters of liquefied natural gas and the largest onshore natural gas well was recently discovered in southern Trinidad. This has allowed Trinidad to capitalize on the biggest mineral reserves within its territories. It is an oil-rich country and stable economically.
