Sugar was the traditional mainstay of the Saint Kitts economy until the 1970s. Although the crop still dominates the agricultural sector, activities such as tourism, export-oriented manufacturing, and offshore banking have assumed larger roles in the economy. As tourism revenues are now the chief source of the islands' foreign exchange, a decline in stopover tourist arrivals following the 11 September 2001 terrorist attacks has eroded government finances. The opening of a 1,000+ bed Marriott hotel in February 2003 was expected to bring in much-needed revenue.
