The largest sea port in the country, Chittagong is the main route for almost all of Bangladesh's imports and exports, and generates a huge amount of revenue each year, attracting many investors internationally.citation needed] Its harbour also contains extensively developed port facilities, and is particularly suitable for ocean steamers.
Chittagong is also Bangladesh's commercial and manufacturing centre, and home to the country's largest companies. Notably, two large eco-parks catering to ecologists and forestry-related genetic science have been opened recently in neighbouring Sitakunda and Bashkhali.
