Japan will continue to make a positive contribution to U.N. peacekeeping efforts following its withdrawal of troops from a mission in South Sudan, Foreign Minister Taro Kono said Wednesday in New York.

"Under the banner of 'proactive contribution to peace,' Japan has made every effort to achieve peace and stability in the international community ... we will continue to contribute proactively in peacekeeping activities," Kono said at a U.N. Security Council high-level debate during the General Assembly's general debate week.

The council adopted a peacekeeping reform resolution Wednesday amid calls for change to the system, including from Secretary General Antonio Guterres.
