With the growing unrest in Eastern Europe and the Soviet Union, in 1989, the PDR Lao government reached agreement with the World Bank and the International Monetary Fund on additional reforms. The government agreed to introduce fiscal and monetary reform, promote private enterprise and foreign investment, privatize or close state firms, and strengthen banking. It also agreed to maintain a market exchange rate, reduce tariffs, and eliminate unneeded trade regulations. A liberal foreign investment code was also enacted. Enforcement of intellectual property rights is governed by two Prime Minister's Decrees dating from 1995 and 2002.
