Rizhao is a prefecture-level city in southeastern Shandong province, People's Republic of China. It is situated on the coastline along the Yellow Sea, borders Qingdao to the northeast, Weifang to the north, Linyi to the west and southwest, and faces Korea and Japan across the Yellow Sea to the east. Rizhao features a major seaport, located approximately 620 km north of Shanghai, 170 km southwest of Qingdao, and 120 km north of Lianyungang. The seaport serves as a site for loading and unloading iron ore and coal. Other products passing through the harbour include cement, nickel, bauxite, and the like. In 2011 the Port of Rizhao, together with the cities of Qingdao, Weihai and Yantai in East China's Shandong province, signed a strategic alliance with Busan, the largest port of the Republic of Korea. The alliance aims at building a shipping and logistics center in Northeast Asia.
