National Flag: The Flag of the Kingdom of Siam was created during the reign of King Rama II and flew on all Siamese sea-going vessels. The Symbol of a white elephant on a red background was chosen because whites are considered very auspicious by Thais.King Rama II was known as the “White Elephant King” as he had three of these noble animals in his possession during his reign. The five horizontal stripes of three colours: Red, White, and Blue have very significant meanings. Red signifies the life-blood of Thai people. The White stripe symbolizes the purity of Buddhism, the national religion. And the dominant Blue stripe means the Thai King, the monarchy and the important part its plays in the daily life of Thais. The present national Thai flag, the “Tri-Rong” or three sacred colours, was designed by King Rama VI and first used on September 28, 1917. The flag is raised daily at 8.00 a.m. and pulled down at 6.00 p.m. flying all official buildings, public places, large private enterprises and every learning academy. The flag is also flown nationwide on national holidays.

M. the King, as a sign of royal approval to companies that have rendered outstanding economic and charitable services to Thailand. Such an award is rarely bestowed and considered a great honour.
