PHNOM PENH, June 2 (Xinhua) — Revenue from ticket sales to foreign tourists visiting Cambodia's famed Angkor archaeological park hit 28 million U.S. dollars in the first five months of 2016, up 1.3 percent compared to the same period last year, said a press release on Thursday.

The ancient site welcomed some 972,753 foreigners during the January-May period this year, down 0.25 percent compared to the same period last year, said the press release from the state-owned Angkor Enterprise, which is in charge of ticket sales at the park.

The largest sources of foreign tourists to the site are China, South Korea, and Japan.

Located in northwestern Cambodia's Siem Reap province, Angkor archaeological park, inscribed on the UNESCO's World Heritage List in 1992, is the kingdom's most popular tourist destination.

An entrance fee to the site is 20 U.S. dollars per day for a foreigner, 40 dollars for a three-day visit and 60 dollars for a week-long visit.
