The Port of Hong Kong (), located by the South China Sea, is a deepwater seaport dominated by trade in containerised manufactured products, and to a lesser extent raw materials and passengers. A key factor in the economic development of Hong Kong, the natural shelter and deep waters of Victoria Harbour provide ideal conditions for berthing and the handling of all types of vessels. It is one of the busiest ports in the world, in the three categories of shipping movements, cargo handled and passengers carried. This makes Hong Kong a Large-Port Metropolis. Administration Responsibility for administering the port is vested in the Director of Marine. The Port Operations Committee advises him on all matters affecting the efficient operations of the port, except those matters that are the responsibility of the Pilotage Advisory Committee and the Provisional Local Vessels Advisory Committee. The Hong Kong Maritime and Port Board (HKMPB) advises the Government on matters related to port planning and development and promoting Hong Kong as a regional hub port and a leading container port in the world as well as on measures to further develop Hong Kong's maritime industry and to promote Hong Kong's position as an international maritime centre. The HKMPB replaced (in April 2016) the former Hong Kong Maritime Industry Council and Hong Kong Port Development Council and is chaired by the Secretary for Transport and Housing, as they both were. The Marine Department is responsible for ensuring that conditions exist to enable ships to enter the port, work their :cargoes and leave as quickly and as safely as possible. It is concerned with many aspects of safety standards for all classes and types of vessels, from the largest oil-carrying tankers to the smallest passenger-carrying sampans. It also maintains aids to navigation and mooring buoys for seagoing ships, manages three cross-boundary ferry terminals and administers eight public cargo working areas. Shipping Hong Kong is one of several hub ports serving the South-East and East Asia region, and is an economic gateway to mainland China. The port is part of the Maritime Silk Road that runs from the Chinese coast via the Suez Canal to the Mediterranean, there to the Upper Adriatic region of Trieste with its rail connections to Central and Eastern Europe. Hong Kong set a record in its container throughput in 2007 by handling 23.9 million TEUs (20-foot equivalent units of containers), maintaining its status as
