Bokator in the context of Pradal serey

Kun Khmer (Khmer: គុនខ្មែរ [kun kʰmae] lit. 'Khmer martial arts'), or Pradal Serey (Khmer: ប្រដាល់សេរី [prɑɗal seːrəj] lit. 'free boxing'), is a combat sport that originated in Cambodia. The sport consists of stand up striking and clinch fighting, where the objective is to knock an opponent out, force a technical knockout, or win a match by points. The sport was codified in Cambodia by the French colonial administration in the early 20th century, and was derived from centuries-old traditions, namely Bokator, the close-quarter combat system used during the Khmer empire. The official name of the sport in Khmer is Kbach Kun Pradal Khmer (Khmer: ក្បាច់គុនប្រដាល់ខ្មែរ [kʰɓac kun prɑɗal kʰmae] lit. 'Khmer martial art of boxing').
