text: In March 1971, the communists initiated an anti-pornography campaign, and in early 1973, they launched another campaign opposing tax increases and price inflation while advocating for higher wages for workers. Communist volunteers distributed pamphlets at various locations, including shophouses, schools, and the wharf terminal. They also engaged in military operations against police stations and naval bases, resorting to extreme measures such as beheading suspected government informants. The town of Sibu experienced on-and-off 24-hour curfews for several months.
  On 25 March 1973, the Sarawak government, led by Chief Minister Abdul Rahman Ya'kub, began cracking down on communist activities in the Rajang basin by establishing the "Rajang Special Security Area." A day later, the Rajang Security Command (RASCOM) was formed through the cooperation of civil, military, and police command headquarters. By August 1973, several communist members had been captured, and these individuals provided crucial information that further weakened the communist movement.
  On 22 September 1973, Abdul Rahman initiated "Operation Judas," resulting in the capture of 29 people from the town of Sibu, including doctors, lawyers, businessmen, teachers, and one former member of parliament. Following the surrender of a communist movement in Sri Aman on 21 October 1973, communist activities in the Rajang basin began to decline and never fully recovered their previous strength. The communist movement in Sarawak finally came to an end in 1990.
