The economy of Trinidad and Tobago is the third wealthiest in the Caribbean and the fifth-richest by GDP (PPP) per capita in the Americas. Trinidad and Tobago is recognised as a high-income economy by the World Bank. Unlike most of the English-speaking Caribbean, the country's economy is primarily industrial, with an emphasis on petroleum and petrochemicals. The country's wealth is attributed to its large reserves and exploitation of oil and natural gas. Trinidad and Tobago has earned a reputation as an excellent investment site for international businesses and has one of the highest growth rates and per capita incomes in Latin America. Recent growth has been fueled by investments in liquefied natural gas (LNG) and petrochemicals. Additional petrochemical, aluminium, and plastics projects are in various stages of planning. Trinidad and Tobago is the largest Caribbean producer of natural gas in CARICOM and the second largest producer of oil after Guyana, and its economy is heavily dependent upon these resources. It also supplies manufactured goods, notably food and beverages, as well as cement to the Caribbean region. Oil and gas account for about 40% of GDP and 80% of exports, but only 5% of employment. Regional financial center The country is also a regional financial center, and tourism is a growing sector, although it is not proportionately as important as in many other Caribbean islands. The economy benefits from a growing trade surplus. Economic growth reached 12.6% in 2006 and 5.5% in 2007 as prices for oil, petrochemicals, and LNG remained high, and as foreign direct investment continued to grow to support expanded capacity in the energy sector. Trinidad and Tobago's infrastructure is adequate by regional standards. A major expansion of the Piarco International Airport in Trinidad, the country's main airport, was completed in 2001. There is an extensive network of paved roads, and utilities which are fairly reliable in the cities. Some areas, however, especially rural districts, still suffer from water shortages. The government is addressing this problem with the construction of additional desalinization plants. Infrastructure improvement, especially rural roads and telephone service, drainage, and sewerage, are among the government's budget priorities. Communications and mobile Trinidad and Tobago has a relatively modern, robust and reliable Information and Communications Technology (ICT) infrastructure. Mobile phone service is widespread and has been the major area of growth for several years. Digicel and Laqtel were granted cellular licenses in 2005, breaking the monopoly of
