SEOUL, South Korea — South Korea on Monday proposed high-level talks with North Korea to discuss holding a new round of reunions of aging Koreans separated by the Korean War six decades ago.

The proposal came on the same day that South Korea pledged to donate $13.3 million to help the World Food Program and the World Health Organization provide nutrients, medicine and other urgent assistance for malnourished babies and nursing mothers in the North.

In a message delivered across the border on Monday, the South’s Unification Ministry suggested that the two governments hold high-level talks on Aug. 19 at Panmunjom, the border village where the armistice ending the Korean War was signed in 1953.

The two Koreas held their last high-level meeting in February. During that meeting, they put aside several years of high tensions incited by the North’s nuclear tests and armed provocations against the South and reached an agreement that allowed hundreds of people from both sides to meet their long-lost relatives for the first time since the war.
