Cambodia's real GDP grew at 5.5% in 2002 and 5.2% in 2003, with almost all of the growth coming from the garment sector. Growth in 2004 was strong at 5.5%, with the garment sector providing the biggest input into GDP growth. Inflation moderated from 3% in 2002 to an estimated average of 1.3% over 2003. Inflation remained under control in 2004. The national currency, the riel, was relatively stable over 2002 but depreciated slightly against the U.S. dollar in 2003. The National Bank of Cambodia made a series of limited yet effective interventions in 2004 to keep the riel to dollar rate at roughly 4,000 to one. The economy is heavily dollarized; the dollar and riel can be used interchangeably. Cambodia remains heavily reliant on foreign assistance--about half of the central government budget depends on donor assistance. Cambodia has had trouble attracting foreign direct investment (FDI), due in part to the unreliable legal environment. New FDI levels fell steadily from 1999-2001. According to the National Bank of Cambodia (NBC), which tracks actual monies spent as FDI rather than simply the value of approved FDI projects, in 2001 there was $150 million in FDI. In 2002, the NBC recorded $54 million in FDI. In 2004, FDI was measured officially at $131 million, with over half of that being invested in the garment sector. The economy also has a poor track record in creating jobs in the formal sector, and the challenge will only become more daunting in the future since 50% of the population is under 20 years of age and large numbers of job seekers will begin to enter the work force each year over the next 10 years.
