Tourism is an important foreign currency earner (外汇收入) for Cambodia. More than 1,000,000foreign people are going to visit it this year, and most of them are from South Korea, Japan and the United States. More than half of visitors will visit the Angkor Wat temples.
Now visitors must walk out of Angkor Wat temples at sunset, but Cambodia is going to extend (延长) the visiting hours to as late as 8:30p. m.
