WASHINGTON -- US Secretary of State Rex Tillerson will deliver a speech this week on the role of the South Korea-US alliance in addressing growing threats from North Korea, organizers said Sunday.

Tillerson will be one of two keynote speakers at a forum organized by the Korea Foundation and the Atlantic Council think tank in Washington on Tuesday, according to the KF. The other speaker will be US Secretary of Commerce Wilbur Ross, who is scheduled to address the bilateral trade relationship.

"(Tillerson) will explore the near- and longer-term outlook for the United States to maintain a strong presence within an uncertain and dynamic security environment in the Asia-Pacific, especially through its alliances and partnerships in the region, with a focus on the United States and ROK," KF said in a press release.
