via Khmer Times, 4 Mar 2019: The move is to stem littering in the Angkor complex.

The Apsara Authority has banned visitors from eating food in the World-heritage temple complex.

Hang Pov, Apsara Authority director, said in a letter dated Thursday that the authority wished to remind relevant parties that the Angkor area is a World Heritage Site with many famous temples, especially Angkor Wat, and that eating food in the complex is now banned.

“In order to preserve the precious Khmer legacy and to maintain public order and good sanitation, we ban all food, especially packed meals brought in during sunrise or sunset visits, in the temple complex,” he said.
