Oman's Basic Statute of the State expresses in Article 11 that the "national economy is based on justice and the principles of a free economy." By regional standards, Oman has a relatively diversified economy, but remains dependent on oil exports. In terms of monetary value, mineral fuels accounted for 82.2 percent of total product exports in 2018. Tourism is the fastest-growing industry in Oman. Other sources of income, agriculture and industry, are small in comparison and account for less than 1% of the country's exports, but diversification is seen as a priority by the government. Agriculture, often subsistence in its character, produces dates, limes, grains and vegetables, but with less than 1% of the country under cultivation, Oman is likely to remain a net importer of food.
