Revenue from ticket sales to foreigners visiting Cambodia's Angkor archeological park rose to $45.9 million dollars in the first five months of 2017, up 64 percent compared to the same period last year, according to an official report released on Thursday.

The ancient park welcomed 1.09 million international tourists during the January-May period this year, up 12 percent over the same period last year, said the report of the state-owned Angkor Enterprise.

Most tourists to the park are Chinese, South Koreans and Americans.

The remarkable increase in the revenue was due to the hike in ticket prices since February. A current entrance fee to the site is $37 dollars for a one-day visit, 62 U.S. dollars for a three-day pass, and $72 dollars for a week-long pass.

Entry is free for Cambodians and children under 12 years old.

Located in northwestern Cambodia's Siem Reap province, the Angkor archeological park, inscribed on the World Heritage List of the United Nations Educational, Scientific and Cultural Organization in 1992, is the kingdom's top tourist destination.
