Which is the busiest port in Bangladesh and the third in South Asia, serving as a key hub for the country's imports and exports?

The Chittagong Port (Bengali: চট্টগ্রাম বন্দর) is the main seaport of Bangladesh. Located in Bangladesh's port city of Chittagong and on the banks of the Karnaphuli River, the port handles over 90 percent of Bangladesh's export-import trade, and has been used by India, Nepal and Bhutan for transshipment. According to Lloyd's, it ranked as the 58th busiest container port in the world in 2019. The port has a recorded history dating back to ancient Roman accounts. It is the busiest container port on the Bay of Bengal.
