Ok, here's the magical cow story, just to illustrate how silly cultural animosity can be.
Thais and Cambodians have a long history of cultural mistrust. However it originated long before the lines on the map we know today existed. Angkor Wat is often pivotal in their dislike for one another because it was sacked in the 12th century by the Chams (the traditional Khmer enemy) however, both these national identities have been absorbed into what we know today as Thailand, Vietnam and of Cambodia (Khmer to a lesser extent, but that's a different story.) To this day arguments still arise as to who "owns" this amazing complex.
So anyway, Thailand and Cambodia argue periodically, often shutting down each others embassy, or kicking out each others foreign workers. They also like to take little pot shots at each other through the press. A good example of this was when Cambodia discovered a magical cow (for want of a better description) in Phum Trapeang Chum.
Both countries have a tradition of animist beliefs in rural areas so this in itself was not uncommon. People were coming from all around to be healed by the magic cow. It was widely reported in the press, both Cambodian and to an small extent internationally. Thailand, however, decided that they couldn't allow their Cambodian brethren to have the upper hand, so soon after both the local language and english language thai press reported that the Cambodian magic cow was a fake.
Their reasoning was because a magical cow had already been discovered in rural Thailand the previous year, and everyone knows you can't have more than one magical cow
Sometimes mistrust or dislike of other cultures (although perhaps based on a legitimate reason) can be taken to ridiculous levels. Although personally, I reckon they should introduce the two cows to each other
