Port Klang Authority has identified additional facilities as part of its supply-driven policies. When Westport is completed, the facilities at Port Klang will be sufficient to handle the projected cargo throughput 130.5 million tonnes by the year 2010. Container projection by then will be 8.4 million TEUs.

As part of the master plan, the development of Port Klang will also see further expansion of port facilities south of Port Klang between Tanjung Rhu and Batu Laut (30 km from Port Klang). The major thrust of these developments will be more industrial based dealing with very large consignments.

Port Klang's development is in line with the economic growth in the central region of the country and also its identity as a regional transshipment base.
