South Korean National Intelligence Service Director Suh Hoon met his North Korean counterpart, Jang Kum-chol, the head of the North's United Front Department (UFD), Yonhap News Agency said, citing a government source.

During the meeting, Suh said that he hoped for better inter-Korean ties.

The sides, however, did not discuss the summit, the source added.

The second round of denuclearization talks between Trump and Kim concluded in Hanoi in late February. Though the meeting started on a high note, it ended abruptly, without any deal.
