Tanjung Manis (originally named Tanjung Mani) has a long history of being a port of calls for vessels to collect timber, mainly logs for export. In its heyday, especially in the 1960s and 1970s, active timber trades took place in Tanjung Manis. After a feasibility study has been carried out on the area, the State Government decided to develop a deep sea port at Tanjung Manis to kickstart the overall development of Batang Rajang/ Batang Igan area.
