support has been invaluable to Beijing's effort to claim disputed areas in the South China Sea. Because Cambodia is a member of ASEAN, and because under ASEAN rules "the objections of one member can thwart any group initiative", Cambodia is diplomatically useful to China as a counterweight to southeast Asian nations that have closer ties to the United States. Military The Royal Cambodian Army, Royal Cambodian Navy, Royal Cambodian Air Force and Royal Gendarmerie collectively form the Royal Cambodian Armed Forces, under the command of the Ministry of National Defence, presided over by the Prime Minister of Cambodia. His Majesty King Norodom Sihamoni is the Supreme Commander of the Royal Cambodian Armed Forces (RCAF), and the country's Prime Minister Hun Sen effectively holds the position of commander-in-chief.
