Whakaotihia te rerenga kōrero e whai ake nei: I te marama o Whiringa-a-rangi 1978,
I whakaekehia a Kambodia hei whakautu ki nga whakaekenga rohe a te Khmer Rouge. Ko te People's Republic of Kampuchea (PRK), he kawanatanga a-Soviet i arahina e te Kampuchean People's Revolutionary Party, he roopu i hangaia e nga Vietnamese i te 1951, a i arahina e tetahi roopu Khmer Rouge i rere atu i Cambodia kia kore ai e horoia e Pol Pot me Ta Mok, i whakapumautia. I tino whakawhetai ki te ope ope o Vietnam me te aratohu a te karere o Vietnam ki Phnom Penh. I ahu mai ōna patu i Vietnam me te Soviet Union.
