The minister was speaking on Thursday during the visit to Tanzania of the Democratic Republic of Congo (DRC) President Felix Tshisekedi, who toured the port during his two-day state visit.
Kamwele said the port currently has the capacity to handle between 3000 and 4000 containers per day but after completion of some projects, which the government is undertaking, the port will have the capacity to handle one vessel carrying more than 6000 containers.
According to the minister, the improvement of the port wouldn’t only benefit Tanzanians but also other land locked countries.
He said that some of the projects, which are implemented to improve the port’s capacity include repairing of berths one to eight.
He also pointed out that some infrastructures at the port, which include roads will also be rehabilitated.
Kamwele said: “We are doing all in our capacity to improve the port’s efficiency.”
The port of Dar es Salaam is one of three ocean ports in the country and handles over 90 per cent of the country's cargo traffic.
According to the International Association of Ports and Harbours, it is the fourth largest port on the African Continent's Indian Ocean coastline after Durban, Mombasa and Maputo.
The port acts as a gateway for commerce and trade for Tanzania and numerous bordering landlocked states. For years the inefficiencies at the port has cost the regional economy millions of dollars; in 2012 the total global welfare loss caused by the inefficiencies of the port stood at US$1.8 billion for the Tanzanian economy and 830 million US dollars for the neighbouring countries.
