Foreign Minister Cho Tae-yul and U.S. Secretary of State Antony Blinken met in Seoul on Monday for talks on their countries' bilateral alliance, efforts to deter North Korean threats and other key issues, officials said.

The talks came as South Korea seeks to ensure its alliance with the United States remains strong despite political uncertainties following President Yoon Suk Yeol's impeachment over his failed martial law attempt.

Blinken's visit marked the first trip by a top U.S. official since Yoon's impeachment. Blinken arrived in South Korea late Sunday.

The talks also coincided with North Korea's launch of a ballistic missile into the East Sea, marking its first provocation of the year.

The two top diplomats were to hold a joint press conference following the talks.

Yoon's surprise martial law imposition sparked concerns it could undermine the alliance with Washington and policy coordination on North Korean issues, especially ahead of the launch of the second Donald Trump administration.

The U.S. has reaffirmed its strong support for the "ironclad" alliance with South Korea and voiced confidence in the country's acting leadership, despite the parliamentary impeachment of former acting President Han Duck-soo just less than two weeks after Yoon's impeachment.

Deputy Prime Minister Choi Sang-mok has taken over as the acting president. Blinken paid a courtesy call on Choi ahead of his talks with Cho.

The allies have agreed to fully resume bilateral diplomatic and security schedules postponed in the aftermath of the martial law debacle.

Monday's talks were likely to focus on reaffirming their commitment to the alliance and Washington's deterrence against Pyongyang despite the political situation.

Cho and Blinken were also expected to discuss the deepening military cooperation between the North and Russia, as well as Pyongyang's troop deployment to Russia in support of its war against Ukraine.

They were also expected to underscore their commitment to advancing trilateral cooperation with Japan, a key diplomatic achievement for the outgoing Biden administration and its two Asian allies.

Announcing the visit last week, U.S. State Department spokesperson Matthew Miller said Blinken will meet Seoul officials to discuss ways the two nations can "build our critical cooperation on challenges around the world."

The talks will also address strengthening efforts to promote a free, open and prosperous Indo-Pacific, as well as trilateral efforts with Japan, Miller said.

Blinken is on a three-nation tour this week, with planned stops in Japan and France. The trip is widely expected to be his final overseas visit as the top U.S. diplomat under the Biden administration. (Yonhap)
