Due to geographic restrictions prior to 1983, the development of the Port of Kaohsiung was limited to the northeast bank of the fairway. The Chichin District, on the southwest bank, was largely sidestepped by construction of the No. 2 Entrance in 1969. The port reopened the Chung-Hsin Commercial Harbor Area as Container Terminal No. 4 in 1983 in order to facilitate equitable harbor development on both sides of the main fairway, improve overall utilization of port land, attract more container shipping business, and expand services available to shipping customers.
