Despite its stated wish to contest the 1993 elections, the Khmer Rouge soon ran into various disputes with United Nations authorities in Cambodia, culminating in their desire to boycott the elections. Subsequently, UNTAC decided not to conduct elections in areas under CNUP control.[6] At the time it was estimated that approximately six percent of the population in Cambodia lived in areas under Khmer Rouge control.[7] In July 1994, the PDK was declared illegal by the government, and the self-proclaimed "Provisional Government of National Union and National Salvation of Cambodia" was subsequently set up with involvement by CNUP members.[8]
