Egypt's economy depends mainly on agriculture, media, petroleum exports, exports of natural gas, and tourism; there are also more than three million Egyptians working abroad, mainly in Saudi Arabia, the Persian Gulf and Europe. The completion of the Aswan High Dam in 1970 and the resultant Lake Nasser have altered the time-honored place of the Nile River in the agriculture and ecology of Egypt. A rapidly growing population, limited arable land, and dependence on the Nile all continue to overtax resources and stress the economy.
The government has invested in communications and physical infrastructure. Egypt has received U.S. foreign aid (since 1979, an average of $2.2 billion per year) and is the third-largest recipient of such funds from the United States following the Iraq war. Its main revenues however come from tourism as well as traffic that goes through the Suez Canal.
Egypt has a developed energy market based on coal, oil, natural gas, and hydro power. Substantial coal deposits are in the northeast Sinai, and are mined at the rate of about 600,000 metric tons (590,000 long tons; 660,000 short tons) per year. Oil and gas are produced in the western desert regions, the Gulf of Suez, and the Nile Delta. Egypt has huge reserves of gas, estimated at 1,940 cubic kilometres (470 cu mi), and LNG is exported to many countries.
Economic conditions have started to improve considerably after a period of stagnation from the adoption of more liberal economic policies by the Government, as well as increased revenues from tourism and a booming stock market. In its annual report, the International Monetary Fund (IMF) has rated Egypt as one of the top countries in the world undertaking economic reforms. Some major economic reforms taken by the new government since 2003 include a dramatic slashing of customs and tariffs. A new taxation law implemented in 2005 decreased corporate taxes from 40% to the current 20%, resulting in a stated 100%
