However by a vote of 79 in favor to 28 against with 33 abstentions , the United Nations General Assembly adopted resolution 41/38 which " condemns the military attack perpetrated against the Socialist People 's Libyan Arab Jamahiriya on 15 April 1986 , which constitutes a violation of the Charter of the United Nations and of international law . " Reagan sought to apply the Reagan Doctrine of aiding anti-Soviet resistance movements abroad to Cambodia , which was under Vietnamese occupation after having ousted Pol Pot 's communist Khmer Rouge regime which had perpetrated the Cambodian genocide . The Vietnamese had installed the communist PRK government led by Salvation Front dissident Heng Samrin . According to R. J. Rummel , the Vietnamese invasion , occupation , puppet regime , ongoing guerrilla warfare , and ensuing famine killed 1.2 million Cambodians in addition to the roughly 2 million who had been killed by the Khmer Rouge . The largest resistance movement fighting the PRK government was largely made up of members of the China-backed , former Khmer Rouge regime , whose human rights record was among the worst of the 20th century
