Social dances are those performed by guests at banquets, parties or other informal social gatherings. Khmer traditional social dances are analogous to those of other Southeast Asian nations. Examples include the circle dances Romvong and Romkbach as well as ''Saravan'' and ''Lam Leav''. Modern western popular dances including Cha-cha, Bolero, and the Madison, have also influenced Cambodian social dance.
