I also forgot to add that Maersk and Cosco( China Ocean Shipping Company ) the largest shipping companies in the world. have formed a joint venture in Kenya dubbed Mashariki that makes Mombasa port the hub for those two shipping companies with direct trips between asia and east africa. The Asian shipping lines ASEA and JEDDX have also introduced direct trips to Mombasa Port and they are also in talks with KPA (Kenya ports Authority) to use the port as their hub in east africa . This is due to the diplomatic skills of GOK to attract investors.
This shows port business is not just about price. efficiency and diplomacy also play an important role.
