PHNOM PENH, Cambodia — Cambodia’s government says visitors to the famed Angkor temple complex will have to pay almost twice as much for admission starting next February.

The government said in a statement Friday that the price of single-day tickets will rise from $20 currently to $37. A three-day pass will cost $62, up from $40. The price of a 7-day ticket, valid over a one-month period, will go up from $60 to $72.

No explanation was given for the increase. The government said $2 from each ticket sold will be donated to a Swiss-owned children’s hospital, Kantha Bopha, which provides free treatment.

Last year, about 2.1 million tourists visited Angkor Wat, the spiritual centre of the Khmer ****** that dominated the region from the 9th to 15th centuries.
