Cambodia's economy slowed dramatically in 1997-1998 due to the regional economic crisis, civil violence, and political infighting. Foreign investment and tourism fell off. In 1999, the first full year of peace in 30 years, progress was made on economic reforms. Growth resumed and has remained about 5.0% during 2000-2003. Tourism was Cambodia's fastest growing industry, with arrivals up 34% in 2000 and up another 40% in 2001 before the 11 September 2001 terrorist attacks in the US. Cambodia expects 1 million foreign tourists in 2004. Economic growth has been largely driven by expansion in the clothing sector and tourism. Clothing exports were fostered by the U.S.-Cambodian Bilateral Textile Agreement signed in 1999. Even given Cambodia's recent growth, the long-term development of the economy after decades of war remains a daunting challenge. The population lacks education and productive skills, particularly in the poverty-ridden countryside, which suffers from an almost total lack of basic infrastructure. Fear of renewed political instability and a dysfunctional legal system coupled with government corruption discourage foreign investment. The Cambodian government continues to work with bilateral and multilateral donors to address the country's many pressing needs. The major economic challenge for Cambodia over the next decade will be fashioning an economic environment in which the private sector can create enough jobs to handle Cambodia's demographic imbalance. About 60% of the population is 20 years or younger; most of these citizens will seek to enter the workforce over the course of the next 10 years.
