DURING THE RECENT World Cup, Thailand's hugely enthusiastic football supporters were ambushed in the intervals by a television advertisement showing Thai-speaking foreigners explaining classic aspects of Thai culture to Thais.
In perhaps the most memorable segment a farang - a Westerner - is shown teaching a young Thai man how to smile. Not just any smile but a 'Yim Siam', a Thai smile that comes from the heart.
In other scenes Westerners explained the subtleties of Thai cooking, dancing, 'correct behaviour' and so on.
It ended with a black screen and the words 'Aren't you ashamed?' before closing with the name of their sponsor, Krung Thai Bank.
The advertisement, repeated many times in the following weeks, was rather shocking - foreigners who happened to catch some Thai language television wondered what exactly it was trying to say.
Not a few detected a whiff of racism in the air. Was this state-owned bank jumping on an anti-foreigner bandwagon trundled out following last year's election victory by what some observers have described as the blatantly chauvinist Thai Rak Thai (Thais Love Thais) party?
