The UN Security Council in a statement on Friday condemned the attack but did not explicitly blame the North.
North Korea denies it was involved in the sinking and has accused the South of masterminding a fabrication for political gain.
North Korea first rejected the call by the UN Command to meet and discuss any violation of the armistice ending the 1950-53 Korean War. It later changed its position and said it would accept such a meeting, after Seoul rejected its proposal to send a military team to inspect the sunken ship.
The meeting will take place at the Panmunjom truce village that straddles the military border between the two Koreas at 0100 GMT, Tuesday, the UN Command said.
