US diplomat to visit Seoul to launch working groups on summit agreements

By Song Sang-ho

WASHINGTON, May 19 (Yonhap) -- A senior U.S. diplomat will visit Seoul in the coming weeks to launch bilateral working groups to implement agreements from a summit between South Korean President Lee Jae Myung and U.S. President Donald Trump in October, the State Department said Tuesday.

Under Secretary of State for Political Affairs Allison Hooker will lead a U.S. interagency delegation to the South Korean capital, the department said, after she and Seoul's First Vice Foreign Minister Park Yoon-joo held talks in Washington.

Park arrived in the U.S. capital on Monday apparently as part of efforts to make progress in the implementation of the summit agreements, including U.S. cooperation on Seoul's push to build nuclear-powered submarines and secure rights to civil uranium enrichment and spent nuclear fuel reprocessing for peaceful purposes.

"Under Secretary Hooker will lead an interagency delegation to Seoul in the coming weeks to continue implementing understandings from President Trump's October 2025 visit to the ROK," the department said in a media note. ROK is short for South Korea's official name, the Republic of Korea.

During their talks, Park and Hooker discussed efforts to advance the "broad and enduring" alliance between the two countries, including in security and economic cooperation, it said.

Both sides reaffirmed the importance of ensuring the freedom of navigation through the Strait of Hormuz and in global waterways, according to the department.

The U.S. side reaffirmed its commitment to the defense of South Korea, including through its "extended deterrence" commitments. Extended deterrence means the U.S.' commitment to using the full range of its military capabilities, including nuclear arms, to defend its Asian ally.

At the talks, Hooker emphasized that the U.S. expects continued progress in the bilateral trade and industrial partnership, and underscored the need to ensure "fair" treatment of U.S. companies and the prompt resolution of market access barriers.
