The other non-communist organisation was the National United Front for an Independent, Peaceful, Neutral, and Cooperative Cambodia, formed by Sihanouk and known by its French acronym FUNCINPEC. The organization was formed after Sihanouk had severed ties with the Khmer Rouge following his representation on its behalf at the UN Security Council. As the leader of FUNCINPEC, Sihanouk called on the UN General Assembly to expel Khmer Rouge representatives for their crimes while in power and to keep Kampuchea's seat at the UN vacant on the basis that neither the Khmer Rouge nor the Vietnamese-installed PRK had the mandate to represent the Kampuchean people. He also criticised ASEAN for its continued recognition of the Khmer Rouge, and specifically Thailand for enabling Chinese arms shipments to travel through its territory to supply the notorious communist group. Despite the strength, effectiveness and popularity of the KPNLF and the FUNCINPEC, both resistance groups were plagued by internal divisions caused by the lack of unity, leadership struggles, corruption and alleged abuses of human rights.
