City authorities met with construction companies on Wednesday to discuss concerns that plans to build tall structures near Phnom Penh International Airport could obstruct aircraft flight paths. Three building projects – Camko City, De Castle Diamond and Sky – were addressed in the meeting, with Phnom Penh Deputy Governor Pa Socheatvong saying City Hall had granted licences for the projects but had been unaware of the potential problem. Mao Havannall, a secretary of state for civil aviation, said tall buildings near the airport could pose dangers at night or in bad weather.
