Thai ghost masks used in a traditional festival in Loei, called Phi Ta Khon, are to be given a place of honour at the famed Hahoe Mask Museum in South Korea's northern city of Andong.

"Thai Khon masks will be exhibited at the museum, too," Culture Ministry permanent secretary Vira Rojpojchanarat said yesterday.

He said Thailand had agreed to a request by South Korea's Culture Ministry that the masks be exhibited at the museum, which displays masks from Korea and many other countries.

Vira said South Korea would also send 20 of its masked performers to join the Phi Ta Khon festival in Loei next weekend.

The festival is unique to the Dan Sai district in Loei province and reflects the local Isaan belief in ghosts and spirits. Held once a year, it is part of a grand merit-making festival known as the "Boon Luang" festival.

The origins of the Phi Ta Khon Festival can be found in the tale of Lord Buddha's last great incarnation before attaining enlightenment. In Buddhist accounts, it is said that when Prince Vessandara, the Buddha's penultimate incarnation, returned to his city, it was such a joyous occasion that the village spirits came forth to join the welcoming parade.

In a lively re-enactment of the tale, the young men of the community dress up as "spirits" wearing long trailing costumes made from colourful strips of cloth sewn together.

Meanwhile, Culture Minister Khunying Khaisri Sriaroon disclosed that Thailand was going to participate in the 41st Annual Smithsonian Folklife Festival at the National Mall in Washington.

The festival will be held outdoors between June 27 and July 1, and from July 4 to July 8.

Princess Maha Chakri Sirindhorn Anthropology Centre director Paritta Chalermpow Koanantakool said Thailand would participate in the Mekong River Connecting Culture theme at the festival.

She said the Smithsonian Folklife Festival would attract thousands of visitors.
