Korea demonstrated its democratic resilience and the United States is ready to work with acting President Han Duck-soo, the top U.S. diplomat said Saturday after the National Assembly voted to impeach President Yoon Suk Yeol over his botched martial law attempt.

Secretary of State Antony Blinken made the remarks during a press conference in Aqaba, Jordan, reiterating America's commitment to the "ironclad" alliance with Korea.

"I think the most important thing is that the Republic of Korea (ROK) has demonstrated its democratic resilience. We've seen it follow peacefully, a process laid out in its Constitution," Blinken said, referring to Korea by its official name.

"We are ready to work with President Han as he assumes office," he added.

The secretary voiced strong support for Korean people and the long-standing partnership between the two countries.

"We strongly support the ironclad alliance that joins our two countries together, and it's done so much over the last few years," he said.

In a separate statement, Matthew Miller, the spokesperson for the State Department, reiterated the U.S.' backing for South Korea, its citizens, democratic processes and the rule of law.

"Our commitment to the U.S.-ROK Alliance is ironclad. In recent years, that Alliance has made enormous strides, and the United States looks forward to partnering with the ROK on achieving further progress," Miller said.

"We stand ready to continue this work with Acting President Han Duck-soo and the ROK government to advance our mutual interests and shared values."

Korea's legislature passed the impeachment motion against Yoon hours earlier, suspending him from presidential duties until the Constitutional Court decides whether to unseat him or return him back to office. Han has taken over as the acting president.

Yoon declared emergency martial law on Dec. 3 only to retract the decree hours later following social and political blowback. He has defended his martial law declaration as "an act of governance." (Yonhap)
