Thailand and Cambodia have laid claim to several undemarcated points along their 508-mile (817-kilometer) land border.  

The two neighbors have repeatedly clashed over territory. One of the flashpoints is the Hindu temple Preah Vihear, known as Khao Phra Viharn in Thailand.   

The temple was judged by the International Court of Justiceto belong to Cambodia, though the surrounding land remains disputed.  

Other contested ancient temples include the Ta Muen temple complex and Ta Krabei temple or Prasat Ta Kwai.
