In the early days, Chinese Foochow settlers in Sibu tried to convert the town into a rice cultivation centre. However, this vision did not materialise because the soil was not suitable for rice cultivation. In August 1909, Charles Brooke agreed to grant land titles to Sibu Chinese farmers and encouraged them to cultivate rubber plantations. The rise of rubber prices from 1909 to 1911 had encouraged another 2,000 Foochow settles to come to Sibu. The demand for rubber rose again during Korean War between 1950 and 1953 and has benefited Sibu rubber plantations. Local farmers later used the profits from rubber plantations into setting up shops at Sungai Merah and Durin bazaars and involve in more profitable timber industry. During the Sarawak Communist Insurgency in the 1970s, rural farmers had to abandon their rubber plantations because of martial law declared by the state government which forbade them for helping the communists operating in the jungles.
