Relations between which of the following two countries are strained by a territorial dispute centered on the ancient Preah Vihear temple on their shared border?

The Preah Vihear Temple is a Khmer temple in the Preah Vihear province of Cambodia near the border with Thailand. In 1962, following a significant dispute between Thailand and Cambodia over ownership of the temple, the International Court of Justice (ICJ) in The Hague awarded the ownership to Cambodia. On July 7, 2008, Preah Vihear was listed as a UNESCO World Heritage Site.
