In Cambodia, ceremony of the klèng (kite, inCambodia) was practised until the death of king Ang-Duong in1859. At the time of full moon of November, the priests were invited to take their meal with the palate and, at the fallen night, the king and his mandarins launched the kites to the celestial spirits.

The season of the takes-off of the large kites is in November when rice harvests are finished. The villagers build the kites in group and especially make them fly during the night to listen to the song of the sound arcs, named "èk". These arcs of bamboos carry a long plate of cane or sheet of palm tree which, behaviour by a wire at each end, can swivel on itself and produces a soft random melody.

At the time of the old civilization Khmer, of IXe in XIIe century, the kite was, as often in Asia, used with a religious view. During royal ceremonies, behaviours by the priests bhramanes, the Khmers made fly the kites provided with sound arcs and, of their flight, the bonzes forecast dryness or rains for the year to come. A rite taken again besides by the invaders Thai at the time of the first kingdom of Sukhothai.
