Cambodia's per capita income is rapidly increasing, but is low compared with other countries in the region. Most rural households depend on agriculture and its related sub-sectors. Rice, fish, timber, garments and rubber are Cambodia's major exports. The International Rice Research Institute (IRRI) reintroduced more than 750 traditional rice varieties to Cambodia from its rice seed bank in the Philippines. These varieties had been collected in the 1960s.

In 1987, the Australian government funded IRRI to assist Cambodia in improving its rice production. By 2000, Cambodia was once again self-sufficient in rice. However, few Cambodian farmers grow other crops leaving them vulnerable to crop failures. In recent years, various international aid organizations have begun crop diversification programs to encourage farmers to grow other crops. The recovery of Cambodia's economy slowed dramatically in 1997–98, because of the regional economic crisis, civil violence, and political infighting. Foreign investment and tourism also fell off drastically. Since then however, growth has been steady. In 1999, the first full year of peace in 30 years, progress was made on economic reforms and animal growth resumed at 5.0%.

Despite severe flooding, GDP grew at 5.0% in 2000, 6.3% in 2001, and 5.2% in 2002. Tourism was Cambodia's fastest growing industry, with arrivals increasing from 219,000 in 1997 to 1,055,000 in 2004. During 2003 and 2004 the economic growth rate remained steady at 5.0%, while in 2004 inflation was at 1.7% and exports at $1.6 billion USD. As of 2005, GDP per capita in PPP terms was $2,200, which ranked 178th (out of 233) countries. The older population often lacks education, particularly in the countryside, which suffers from a lack of basic infrastructure. Fear of renewed political instability and corruption within the government discourage foreign investment and delay foreign aid, although there has been significant assistance from bilateral and multilateral donors. Donors pledged $504 million to the country in 2004, while the Asian Development Bank alone has provided $850 million in loans, grants, and technical assistance
