In late September, 1960, twenty-one leaders of the KPRP held a secret congress in a vacant room of the Phnom Penh railroad station. This pivotal event remains shrouded in mystery because its outcome has become an object of contention (and considerable historical rewriting) between pro-Vietnamese and anti-Vietnamese Khmer communist factions. The question of cooperation with, or resistance to, Sihanouk was thoroughly discussed. Tou Samouth, who advocated a policy of cooperation, was elected general secretary of the KPRP that was renamed the Workers' Party of Kampuchea (WPK). His ally, Nuon Chea (also known as Long Reth), became deputy general secretary; however, Pol Pot and Ieng Sary were named to the Political Bureau to occupy the third and the fifth highest positions in the renamed party's hierarchy. The name change is significant. By calling itself a workers' party, the Cambodian movement claimed equal status with the Vietnam Workers' Party. The pro-Vietnamese regime of the People's Republic of Kampuchea (PRK) implied in the 1980s that the September 1960 meeting was nothing more than the second congress of the KPRP.
