Japan will deal sincerely with issues from the past concerning South Korea and work to improve bilateral relations by looking to the future, Foreign Minister Taro Aso said Sunday.

In a statement issued on the 40th anniversary of normalization of diplomatic ties between Japan and South Korea, Aso also called for continued cooperation on multilateral issues of common concern, including the North Korean nuclear issue.
