city, eastern Jiangsu sheng (province), China. It is situated on the northern shore of the head of the Yangtze River (Chang Jiang) estuary. Northward, it is connected with the Tongyang and Tonglu canal systems, which serve the coastal zone of Jiangsu north of the Yangtze and connect westward with the Grand Canal. Tiansheng port, about 7.5 miles (12 km) to the west, and Nantong port provide Nantong with ports on the Yangtze. Another port at Langshan, some 8 miles (13 km) south of Nantong, has been developed since the 1990s; this facility has greatly expanded the handling capacity of the ports group administered by the city and has made Nantong one of the largest ports along the Chinese coast.
