Regarding the Siem Reap international airport development project, the group of ad hoc experts maintain a general reminder of the need to respect the integrity of the site and to forbid any flight over the monuments inscribed on the World Heritage List (including the Western Baray, a universal masterpiece of hydraulic engineering).

In technical terms, the experts strongly recommend that the APSARA National Authority, in consultation with “Cambodia Airports,” draw on the expertise of a specialist in airport development on heritage zones. It is recommended that ICOMOS be contacted to arrange this expert mission.
