Oil and natural gas account for almost all exports. Since only a few products other than petroleum are produced locally, a wide variety of items must be imported. Brunei statistics show Singapore as the largest point of origin of imports, accounting for 25% in 1997. However, this figure includes some transshipments, since most of Brunei's imports transit Singapore. Japan and Malaysia were the second-largest suppliers. As in many other countries, Japanese products dominate local markets for motor vehicles, construction equipment, electronic goods, and household appliances. The United States was the third-largest supplier of imports to Brunei in 1998.
