Seoul, South Korea (CNN) -- High-level military officers from the U.S.-led U.N. Command and North Korea are slated to meet Tuesday in the village of Panmunjom in the demilitarized zone between North and South Korea, the United Nations said Monday.

They plan to discuss the March 26 sinking of a South Korean warship, the Cheonan.

The U.N. officers will be U.S. colonels, as the United States holds responsibility for U.N. security forces in Korea.

North Korea has accepted a U.N. proposal for the meeting of colonel-level leaders to be a precursor to talks between generals on the contentious naval incident.
