Tourism is the primary economic activity, accounting for more than 70% of GDP and 70% of employment. The islands normally host 2 million visitors a year. The manufacturing sector consists of petroleum refining, textiles, electronics, pharmaceuticals, and watch assembly. The agricultural sector is small, with most food being imported. International business and financial services are a small but growing component of the economy. One of the world's largest petroleum refineries is at Saint Croix. The islands are subject to substantial damage from storms. The government is working to improve fiscal discipline, support construction projects in the private sector, expand tourist facilities, reduce crime, and protect the environment.
