At present, we can't deny that Thais are not racism other country especially our neighbouring countries due to the story in the past, Thai people proud of independence which not colonised by other nations but many countries such as Myanmar and Laos, colonised by France and England and they was also classified a undeveloped countries While Thailand is a developing countries. Moreover ,I think that thai society divide Social class form career and the lowest career is labor which most of Myanmar and Laos migrants are work much in Thailand so These things have influenced the attitudes of the Thai people that we has superiority and we like to insult them example, We often scolded people uneducated “Myanmar” and the outdated “Laos”. It shows clearly that racism Thailand.
