In 1939 Tanjung Tualang became a major host for the Communist Party of Malaya (CPM).
A well known CPM Malay leader, Rashid Maidin, was recruited here by Tu Lung Shan.
Tanjung Tualang also has a large number of rubber estates (owned individually or by local and multinational corporations).
It is believed that Tanjung Tualang has an "Underground Armament Testing Complex" for the Malaysian government under the purview of the Ministry of Defense.
The actual site for this facility is undisclosed but available clues suggest a nearby area known as Changkat Tin.
