SEOUL, Sept. 11 (Yonhap) -- Seoul shares closed higher on Wednesday to extend their gains to a sixth consecutive day as investors remained confident about the anticipated stimulus measures from the European Central Bank this week. The Korean won rose against the U.S. dollar.

Along with the expected move by the eurozone's central bank, the reconciliation mood between the United States and China over trade also buoyed investor sentiment.
