on September 18, 1979. Saint Lucia does not have a military although the Royal Saint Lucia Police Force has a Special Service Unit (SSU) and a Coast Guard. The island signed the UN Treaty on the Prohibition of Nuclear Weapons in 2018. Economy Saint Lucia is a Small Island Developing State, a designation similar to a developing country with a few substantial differences due to Saint Lucia's island nature. The service sector is the largest sector of the economy, accounting for 86.9% of GDP in 2020, followed by industrial and agricultural sectors at 10.9% and 2.2%, respectively. Saint Lucia has been able to attract foreign business and investment due to its educated workforce and improvements in roads, communications, water supply, sewerage, and port facilities. Like most small islands, Tourism and offshore banking are Saint Lucia's main sources of revenue. Agriculture, specifically the banana industry, was previously the largest sector of the economy, although its importance has declined significantly. The island's manufacturing sector has been called the most diverse in the Eastern Caribbean, with goods such as plastic being produced on a large scale. Saint Lucia's currency is the Eastern Caribbean Dollar (EC$), a regional currency shared among members of the Eastern Caribbean Currency Union (ECU). The country's main trade partners are the US, UK, EU and other CARICOM countries. Tourism Tourism is easily the largest contributor to Saint Lucia's economy. Tourist numbers tend to be more substantial during the dry season (January to April), often referred to as the tourist season. Saint Lucia's tropical weather, scenery, beaches and resorts have made it a popular tourist destination, with 1.29 million visitors arriving in 2019. Some of Saint Lucia's tourist attractions include the Sulphur Springs, the Botanical Gardens, Pigeon Island and The Pitons. Agriculture The agricultural sector was once the main contributor to Saint Lucia's economy. This was especially thanks to the exporting of bananas. However, its importance to the economy has declined significantly, in part due to increased competition from South American countries in the banana industry. Nevertheless, agriculture is still an important part of the country's economy, providing 7.9% of jobs and contributing to 2.2% of the GDP in 2021. About 18% of land is used for agricultural practices. Bananas remain the main agricultural product grown in Saint Lucia, as well as coconuts, cocoa beans, mangoes, avocados, vegetables, citrus fruits, and root crops such as yams and sweet potatoes. Saint
