Oji Paper established Jiangsu Oji Paper Co., Ltd. in 2007 in Nantong, located in southern China, to produce high-quality paper and pulp and support its expanding business in East Asia. Jiangsu Oji Paper began shipments of high-quality paper in January 2011, and is constructing its massive pulp production facilities with an annual production capacity of 0.7 million tons that will begin operations in 2013.
