South Korea's foreign minister said Sunday that the nation is in talks with "related countries" to formally end the Korean War, local media said Wednesday, after an earlier report suggested Seoul was seeking to declare an end to the conflict in late August.

Foreign Minister Kang Kyung-wha remarks were believed to be the first time a top official had confirmed that the ongoing talks were being held since South Korean President Moon Jae-in and North Korean leader Kim Jong Un reached an agreement on the issue at an inter-Korean summit on April 27, the South's Yonhap news agency reported.

At the summit, the first-ever between the two leaders, Moon and Kim agreed that their countries, together with the United States, would seek to formally end the Korean War before the year's end.
