the Vietnamese Marxist–Leninists were committed to pursuing an Indochinese Federation and that their interests were therefore incompatible with Cambodia's. In November 1965, Saloth Sâr flew from Hanoi to Beijing, where his official host was Deng Xiaoping, although most of his meetings were with Peng Zhen. Sâr gained a sympathetic hearing from many in the governing Chinese Communist Party (CCP)—especially Chen Boda, Zhang Chunqiao and Kang Sheng—who shared his negative view of Khrushchev amid the Sino-Soviet split. CCP officials also trained him on topics like dictatorship of the proletariat, class struggles and political purge. In Beijing, Sâr witnessed China's ongoing Cultural Revolution, influencing his later policies. Sâr left Beijing in February 1966, and flew back to Hanoi before a four-month journey along the Ho Chi Minh Trail to reach the Cambodian Marxist–Leninists' new base at Loc Ninh. In October 1966, he and other Cambodian party leaders made several key decisions. They renamed their organisation the Communist Party of Kampuchea (CPK), a decision initially kept secret. Sihanouk began referring to its members as the "Khmer Rouge" ('Red Cambodians'), but they did not adopt this term themselves. It was agreed that they would move their headquarters in Ratanakiri Province, away from the Viet Cong, and that—despite the views of the North Vietnamese—they would command each of the party's zone committees to prepare for the relaunch of armed struggle. North Vietnam refused to assist in this, rejecting their requests for weaponry. In November 1967, Sâr travelled from Tay Ninh to base Office 102 near Kang Lêng. During the journey, he contracted malaria and required a respite in a Viet Cong medical base near Mount Ngork. By December, plans for armed conflict were complete, with the war to begin in the North-West Zone and then spread to other regions. As communication across Cambodia was slow, each Zone would have to operate independently much of the time. Cambodian Civil War Against Sihanouk In January 1968, the war was launched with an attack on the Bay Damran army post south of Battambang. Further attacks targeted police and soldiers and seized weaponry. The government responded with scorched-earth policies, aerially bombarding areas where rebels were active. The army's brutality aided the insurgents' cause; as the uprising spread, over 100,000 villagers joined them. In the summer, Sâr relocated his base north to the more mountainous Naga's Tail, to avoid encroaching government troops. At this base, called K-5, he increased his
