U.S. National Intelligence Director Avril Haines visited the Demilitarized Zone on Thursday.
Although the details of her visit have not been revealed, she is thought to have toured the joint security area in the border village of Panmunjeom.
Haines arrived here on Wednesday following talks in Tokyo with her Japanese and South Korean counterparts to discuss North Korea and other pending issues.
Her visit comes after the U.S. completed its policy review on Pyeongyang, having decided to take a calibrated and practical approach toward complete denuclearization on the Korean Peninsula.
Haines also visited the Defense Intelligence Agency, which is in charge of collecting and analyzing military intelligence.
She met with agency chief Lee Young-choul and other intel-related officials, apparently to discuss ways to boost bilateral cooperation in sharing intelligence on North Korea.
Asked by reporters whether she has any plans to communicate with the North during her stay, she did not reply.
The U.S. intel chief's schedule in South Korea could also include a courtesy call on President Moon Jae-in and a meeting with Seoul's National Security Adviser, Suh Hoon.
Likely to top discussions is Washington's new North Korea policy and final coordination ahead of the South Korea-U.S. summit on May 21st.
Separately, Seoul's National Security Council on Thursday vowed to continue communication and cooperation with related parties for the resumption of dialogue between North Korea and the U.S.,.. as well as between the two Koreas based on Washington's new North Korea policy which focuses on diplomacy and builds upon the Singapore Declaration.
