of the left-wing Liberation League and the "O Members" of the Advanced Youths Association. While they had discussed creating a Communist party in Sarawak, they delayed doing so until 1971 due to the tense political situation in Indonesia. The Sarawak Chief Minister Abdul Rahman Ya'kub also made several overtures to the NKCP insurgents and managed to convince several of the insurgents to lay down their arms. In 1973–74, the Malaysian government scored a key victory when Rahman Ya'kub successfully convinced Bong Kee Chok, the Director and Commissar of the North Kalimantan People's Army, to sign a Memorandum of Understanding with the Sarawak government. Following this event, between 481 and 580 members of the North Kalimantan People's Army and the Sarawak People's Guerillas surrendered and returned to society. This was a heavy loss for the Sarawak Communist Movement since this number comprised approximately 75 per cent of its entire force in Sarawak. After this defection, only 121 guerrilla fighters led by Hung Chu Ting and Wong Lian Kui remained. By 1974, the Communist insurgency had become confined to the Rejang Delta. Both sides sustained casualties and many civilians were also killed and wounded in the cross-fire. Following the successful Hat Yai peace accords between the Malayan Communist Party and the Malaysian government in 1989, the remaining North Kalimantan Communist Party guerillas decided to end their insurgency after one of their Chinese contacts Weng Min Chyuan convinced them to negotiate with the Sarawak state government. In July 1990, a series of negotiations between the NKCP and the Sarawak government took place at the town of Bintulu. By 17 October 1990, a peace agreement formally ending the Sarawak communist insurgency was ratified at Wisma Bapa Malaysia in the state capital Kuching. Shortly afterwards, the last remaining NKCP operatives led by Ang Cho Teng surrendered. These developments ended the Sarawak Communist insurgency.
