FOREIGN TRADE ZONES Among the free trade ports of this class may be mentioned Hong Kong, Weihaiwei, Dairen, and Kowloon, China; Singapore and Malacca, Straits Settlements; and Aden, Arabia. These ports are open to the ships and commerce of the world. Such restrictions as exist apply to specific commodities and not to specific parts of the ports. Another free trade port is Gibraltar, but its use for transshipping purposes, except for business to and from Morocco, is not great. Hong Kong. —The British colony of Hong Kong occupies a unique position in world trade. With the exception of duties on wines and spirits, trade at the port of Hong Kong is wholly free. For this reason it is properly classed as a free trade port and not a free port. Hong Kong is the distributing center for the enormous trade of south China, and about 30 per cent of the entire foreign trade of China passes through the colony. It is essentially an entrep6t where merchandise from all parts of the world is interchanged. The colony produces noth- ing, animal, vegetable or mineral, of any importance from the point of view of world trade. Its local consumption, except in the case of materials for shipbuilding, ship repairing, and ship furnishing, is equally negligible. Such industries as exist are related mainly to the needs of the local population, except the products of the tin and sugar refineries and the tobacco factories, which are destined almost wholly for reexportation. The whole trade of the colony may be regarded as transshipment. Much of the trade out of China is carried by regular lines of river steamers, which require to unload and reload for the return journey with as little delay as possible. Merchants, both native and foreign, give special attention to the assembling and transshipping of mer- chandise to and from all parts of the world, and with the world-wide steamship connections at Hong Kong the necessity for retransship- ment at other ports is reduced to a minimum. Most of the Chinese foreign trade handled in Hong Kong passes the Chinese customs at Canton or Kowloon, but some goes through Foochow, Amoy, Swatow, Samshui, Kongmoon, Wuchow, and a few minor ports. Hong Kong being an island, the terminus of the railroad from Canton is at Kowloon. Weihaiwei, in the province of Shantung, was leased to Great Britain in 1898. The territory leased comprises the port and bay, the island of Liu Kung, all the islands in the bay, and a belt of land 10 miles wide along the entire coast line of the bay. It has an area of 285 square miles. The port is duty free. Dairen and Kowloon are usually classed as free ports. The exemp- tion from customs duties applies only to commerce of these districts. All goods passing in and out of the interior are subject to Chinese duties, which are assessed both on imports and exports. Kowloon is under British control. Dairen and Tsingtau are both practically
