The government of Belize faces important challenges to economic stability. Rapid action to improve tax collection has been promised, but a lack of progress in reining in spending could bring the exchange rate under pressure. The tourist and construction sectors strengthened in early 1999, leading to a preliminary estimate of revived growth at four percent. Infrastructure remains a major economic development challenge; Belize has the region's most expensive electricity. Trade is important and the major trading partners are the United States, Mexico, the United Kingdom, the European Union, and CARICOM.
