In 2011 Cambodia's per capita income in PPP is $2,470 and $1,040 in nominal per capita. Cambodia's per capita income is rapidly increasing but is low compared to 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.Based on the Economist, IMF: Annual average GDP growth for the period 2001–2010 was 7.7% making it one of the world's top ten countries with the highest annual average GDP growth. Tourism was Cambodia's fastest growing industry, with arrivals increasing from 219,000 in 1997 to over 2 million in 2007. In 2004, inflation was at 1.7% and exports at $1.6 billion US$.
China is Cambodia's biggest source of foreign direct investment. China planned to spend $8 billion in 360 projects in the first seven months of 2011. It is also the largest source of foreign aid, providing about $600 million in 2007 and $260 million in 2008.
Oil and natural gas deposits found beneath Cambodia's territorial waters in 2005 yield great potential but remain mostly untapped, due in part to territorial disputes with Thailand.
The National Bank of Cambodia is the central bank of the kingdom and provides regulatory oversight to the country's banking sector and is responsible in part for increasing the foreign direct investment in the country. Between 2010 and 2012 the number of regulated banks and micro-finance institutions increased from 31 covered entities to over 70 individual institutions underlining the growth within the Cambodian banking and finance sector.
In 2012 Credit Bureau Cambodia was established with direct regulatory oversight by the National Bank of Cambodia.The Credit Bureau further increases the transparency and stability within the Cambodian Banking Sector as all banks and microfinance companies are now required by law to report accurate facts and figures relating to loan performance in the country.
One of the largest challenges facing Cambodia is still the fact that 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 aid 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.Bribery are often demanded from companies operating in Cambodia when obtaining licences and permits, such as construction-related permits.
