The economy of Cambodia has seen rapid progress in the last decade. Per capita income, although rapidly increasing, is low compared with most neighbouring countries. The main domestic activity on which most rural households depend is agriculture and its related sub-sectors. Manufacturing output is varied but is not very extensive and is mostly conducted on a small-scale and informal basis. The service sector is heavily concentrated in trading activities and catering-related services. Reuters has reported that oil and natural gas reserves have been found off-shore.
