China's Taizhou Kouan Shipbuilding is said to be in talks with Germany’s Harren & Partner about building more newbuildings.
Details on the ship type, size and price are yet to be revealed.
The German shipowner recently took delivery of the Pabal, the first of two 76,000-dwt ice-class bulk carriers from the yard.
Taizhou Kouan is scheduled to deliver the Pabur, a sistership to the Pabal, in early December.
Both panamaxes were ordered in early 2011 with a charter fixed.
