South and North Korean officials will meet Monday to prepare for a summit between South Korean President Moon Jae-in and North Korean leader Kim Jong Un.

South Korea’s Unification Ministry, which handles relations between the two Koreas, announced the meeting Thursday, The Associated Press reported.

The planned summit between Kim and Moon will be the third such meeting in recent months. The two leaders met in April and held a more informal meeting in May.

An official at the Unification Ministry told the AP that the officials Monday will discuss ways to advance agreements Kim and Moon made at an earlier summit. Those agreements are aimed at reducing tensions between the two countries and included holding a Korean summit in the fall in Pyongyang.

Trump praised Kim after their summit, but since then there has been concern that North Korea is not following through on promises it made.

The Associated Press reported that North Korea is insisting that the U.S. also suspend missile launches and nuclear tests. The Trump administration has refused to lift economic sanctions on the North until it fully denuclearizes.

South Korea urged the North to give up its nuclear weapons Sunday.

The meeting Monday will be held at Tongilgak, which is a North Korean building in the border village of Panmunjom. The Unification Ministry did not identify the officials who will attend. Similar meetings have been conducted by South Korea’s unification minister and his northern equivalent.

Both Koreas have signaled an interest in ending the Korean War, which has been in a ceasefire since 1953.
