from The Century Dictionary and Cyclopedia
- n. A sea- or riverport of one country opened by treaty to the trade and commerce of another. The term is applied more particularly to certain ports of those countries of the far East —for example, China, Korea, and Japan —which at the time of making the treaties were more or less opposed to commercial or any intercourse with other nations. The first treaty-ports of China were opened in accordance with the Anglo-Chinese treaty of Nanking (1842); the first in Japan by Townsend Harris, acting for the United States, in 1858; and the first in Korea by treaty with Japan in 1876.
