Laos is rich in mineral resources and imports petroleum and gas. Metallurgy is an important industry, and the government hopes to attract foreign investment to develop the substantial deposits of coal, gold, bauxite, tin, copper, and other valuable metals. The mining industry of Laos has received prominent attention with foreign direct investments. This sector has made significant contributions to the economic condition of Laos. More than 540 mineral deposits of gold, copper, zinc, lead and other minerals have been identified, explored and mined. In addition, the country's plentiful water resources and mountainous terrain enable it to produce and export large quantities of hydroelectric energy. Of the potential capacity of approximately 18,000 megawatts, around 8,000 megawatts have been committed for export to Thailand and Vietnam. As of 2021, despite cheap hydro power available in the country, Laos continues to also rely on fossil fuels, coal in particular, in the domestic electricity production.
