South Korea will maintain its foreign policy direction, and its diplomatic efforts to engage with the incoming Donald Trump administration will remain steadfast despite President Yoon Suk Yeol's suspension from duties following his impeachment, Foreign Minister Cho Tae-yul said Sunday.

Cho said his potential visit to the United States after Trump's inauguration on Jan. 20 is "under consideration."

"I have already spoken with Secretary of State Antony Blinken, but I believe there are messages that need to be discussed in person, so I will discuss the matter with the U.S. side," he said during a press briefing.

Cho said his ministry "will continue necessary communication, centered around the South Korean Embassy in the U.S."

The briefing came a day after the National Assembly voted in favor of Yoon's impeachment, which held him accountable for his botched declaration of martial law on Dec. 3. Suspended from his duties, Yoon now faces a Constitutional Court ruling that will determine within the next six months whether the impeachment is upheld.

Acting President Han Duck-soo, who assumed leadership as prime minister, held a phone call with U.S. President Joe Biden earlier in the day, during which both leaders reaffirmed the strength of the bilateral alliance.

"Our government will carry out diplomatic and security policies without disruption, ensuring that the South Korea-U.S. alliance continues to be stably maintained and developed," Han said during the phone call, according to his office.

Biden expressed appreciation for Han's explanation of the ongoing situation in Seoul, saying that he trusts South Korea's democracy and praised its resilience.

"I believe concerns about a potential gap in summit diplomacy have been eased by Han's call with Biden this morning," Cho said during the press conference. "The acting leadership system demonstrates that the country's affairs are being handled democratically and in line with constitutional procedures."

He added, "Our commitment is firm to push forward with existing bilateral and multilateral agendas, such as the friendly South Korea-Japan relations and hosting the Asia-Pacific Economic Cooperation summit. Seeing from the reactions of partnering nations, we expect these efforts to proceed smoothly without major obstacles."

Cho acknowledged, however, that "restoring everything to its original state will require time and effort," and vowed to put every effort toward the swift normalization of the nation's diplomacy.

Shortly after the impeachment decision the previous day, Cho met with U.S. Ambassador to South Korea Philip Goldberg to explain the situation and ensure continued communication.

First Vice Foreign Minister Kim Hong-kyun met with Japanese Ambassador Koichi Mizushima, while Deputy Foreign Minister Chung Byung-won held talks with with Fang Kun, charge d'affaires ad interim of the Chinese Embassy.

Cho, who offered to resign on Dec. 4 amid the martial law debacle, reiterated his intention to step down.

"Even now, I have no hesitation in stepping down from my role. But I feel it is my duty to fulfill the responsibilities given to me. Now I find myself in a situation where even my resignation is not entirely my own decision to make," he told reporters.

As he continues to carry out his role as the top diplomat in the faltering Yoon administration, Cho has a lot on his shoulders.

Following Yoon's impeachment, which occurred halfway through his five-year term, South Korea's diplomacy has entered one of its most turbulent periods. In particular, maintaining a robust South Korea-U.S. bilateral alliance under Trump — known for his transactional diplomatic approach — has become trickier.

Trump, who prefers high-profile leader-to-leader engagement, could be reluctant to engage directly with South Korea's acting president.

While Trump has boasted of his personal ties with North Korean leader Kim Jong-un and hinted at resuming direct talks with him, the president-elect has remained relatively silent on issues related to South Korea following his election, including defense cost-sharing. He has not publicly commented on the ongoing political turmoil in Seoul.

However, a senior foreign ministry official viewed that Trump's limited remarks about South Korea do not necessarily imply that Seoul will be sidelined in the new U.S. government's Korean Peninsula affairs.

"We should consider whether it is really beneficial for us to be included in issues that Trump publicly raises," the official said during a closed-door briefing.

"I don't think there is a need for us to bring up issues that have not been mentioned by him and make them widely public. Behind-the-scenes communication is the most appropriate diplomatic approach for the nation's interest."
