The North Kalimantan Communist Party (abbr. NKCP) was a communist political party based in the Malaysian state of Sarawak in northern Borneo. It was formally founded on 19 September 1971. Before that, the group had been operating under the name Sarawak People's Guerrillas. The chairman of the NKCP was Wen Ming Chyuan and the party enjoyed close links with the People's Republic of China. The NKCP's membership was predominantly ethnically Chinese. The two military formations of the NKCP were the Sarawak People's Guerilla Force (SPGF) or Pasukan Gerilya Rakyat Sarawak (PGRS), and the North Kalimantan People's Army (NKPA) or the Pasukan Rakyat Kalimantan Utara (PARAKU). The NKCP participated in the Sarawak Communist Insurgency (1962–1990). On 17 October 1990, the North Kalimantan Communist Party signed a peace agreement with the Sarawak state government, formally ending the Sarawak Communist Insurgency. Name The organisation was initially referred to by its members as the Sarawak Communist Movement and subsequently the North Kalimantan Communist Party after 1970. Documents published by the Sarawak colonial and Malaysian governments tended to label any anti-colonial group operating in Sarawak as either the Sarawak Communist Organisation (SCO) or the Clandestine Communist Organisation (CCO). Due to the Cold War atmosphere, anti-colonial groups and left-leaning individuals were often categorised as Communists by the authorities. According to the Japanese academic Fujio Hara, the NKCP's two main military formations were the Sarawak People's Guerilla Force (SPGF) or Pasukan Gerilya Rakyat Sarawak (PGRS), and the North Kalimantan People's Army (NKPA) or the Pasukan Rakyat Kalimantan Utara (PARAKU). The SPGF operated in western Sarawak while the NKPA operated in eastern Sarawak. In addition, the main component organisations were the Sarawak Liberation League (SLL), the Sarawak Advance Youths' Association (SAYA), and the NKPA. History Origins According to Hong-Kah Fong, the North Kalimantan Communist Party was officially formed on 30 March 1970. However, 19 September 1971 was selected as the official commemoration date in order to commemorate the Pontianak Conference of 17–19 September 1965, which is regarded as the birth date of the Sarawak Communist Movement. The NKCP traces its origins to local Chinese Communists who had migrated from China to Sabah during the 1930s and 1940s. The NKCP was also preceded by several Communist movements including the Races Liberation Front and the Borneo Anti-Japanese League (which consisted of two organisations: the North Borneo Anti Japanese League and the West Borneo Anti-Japanese League), which had resisted the Japanese
