SEOUL, South Korea - The winner of South Korea's upcoming presidential election will be faced with the task of uniting a country riven by political acrimony since the impeachment of former President Yoon Suk Yeol, who sparked national outrage after declaring martial law in December.
But first, they will have to contend with President Donald Trump's tariffs.
On Wednesday, U.S. and South Korean trade officials kicked off a new round of negotiations aimed at reaching a deal by July 8, when Trump's 90-day reprieve for his "liberation day" tariffs expires. South Korea faces a 25% reciprocal tariff rate as well as product-specific duties of 25% for steel, aluminum and automobiles - all of which are major exports.
With the election scheduled for June 3, carrying these talks to the finish line will be the first and most pressing agenda item for South Korea's next president.
For now, officials from the two countries have agreed to expand the talks beyond tariffs rates to include broader topics such as currency exchange rates and economic security - a reflection of Trump's desire for a sweeping realignment of the U.S.–South Korea relationship that he has described as "one-stop shopping."
But there are likely to be further complications.
Trump, who has long griped that South Korea does not pay enough for the upkeep of the 28,500 U.S. troops stationed in the country, has expressed a desire to fold defense cost-sharing into the current talks. Writing on his social media site last month, he said that he had discussed "payment for the big time Military Protection we provide to South Korea" with then-acting President Han Duck-soo.
But with Trump having once claimed he would get Seoul to pay $10 billion a year, the topic has been highly sensitive in South Korea, fueling calls for the country's nuclear self-armament on grounds that the U.S. can no longer be relied upon for military support. There are also concerns in the country that a "package deal" favored by Trump may not work out to Seoul's advantage.
Here's what to know about what South Korea's three leading presidential candidates have said about tariffs and the U.S.-South Korea relationship under Trump.
Lee Jae-myung
The former leader of South Korea's liberal Democratic Party, Lee, 61, is the front-runner in the race, having led by as many as 20 percentage points.
During Trump's first term, Lee, then the mayor of Seongnam, cautioned against what he called "overly submissive attitudes" in the face of demands that South Korea should pay more for the presence of the U.S. military.
"Giving up whatever is demanded of us will only lead to us losing everything," he said. "We need to boldly assert our position."
Lee echoed those sentiments in a presidential debate Sunday, criticizing Han, the former acting president, for reportedly signaling his willingness to renegotiate the latest defense cost-sharing deal between Seoul and Washington.
Under what is known as the Special Measures Agreement, the U.S. has covered 40% to 50% of the total costs of keeping troops in South Korea, according to the U.S. Congressional Research Service.
Under the latest version, which was signed under the outgoing Biden administration and will last from 2026 to 2030, Seoul's annual contribution in the first year will be $1.19 billion, an 8.3% increase from 2025.
Lee, who is running on a platform of pragmatic diplomacy, has also stressed the need to balance South Korea's relationship with the U.S. against those with regional neighbors such as Russia or China.
"The U.S.-South Korea alliance is important, and we need to expand and develop that in the future - from a security alliance into an economic alliance and a comprehensive alliance," he said Sunday. "But that does not mean we can rely exclusively on the U.S.-South Korea alliance."
While describing Trump's tariffs as the "campaign of a madman," Lee has also indicated a willingness to discuss a package deal that spans Trump's Alaska natural gas pipeline project, the defense cost issue and cooperation in shipbuilding.
Lee's camp has said that if elected, he will begin his term by seeking an extension of Trump's 90-day grace period for the tariffs.
"If we win the election we will need time to closely examine the issues at the center of the trade relationship with the U.S. as well as any progress made on the tariff negotiations and come up with alternatives," an official from Lee's camp told the South Korean newspaper Donga Ilbo last week.
Kim Moon-soo
A distant second in the polls, Kim, 73, served as labor minister under the impeached Yoon and is the conservative People Power Party's nominee.
Staying true to the South Korean right's self-identification as the staunchly pro-U.S. political camp, Kim has accused Lee of seeking to curry favor with China at the expense of the U.S.-South Korea relationship.
"Your comments in the past would be considered appalling from the perspective of the U.S.," he told Lee at the debate Sunday.
Unlike Lee, who has warned against rushing into a trade deal in favor of a slower and more strategic approach, Kim has said that he would immediately set up a U.S.-South Korea summit to ink a deal before July 8, if he is elected president.
"I will make sure that tariffs against South Korea are either removed or the lowest out of any country in the world," he said at a recent rally.
To this end, Kim has cast himself as the candidate with the greatest chance of winning over Trump.
During his party's primary debates in April, when asked by the moderator whether he would wear a MAGA hat if Trump requested it during any tariff negotiations, Kim responded: "I would do even more, I would even wear a jumper if he asked."
"The most important thing in negotiating with President Trump is trust," he said Sunday. "Only when both sides can trust each other can the U.S.-South Korea alliance be strengthened, and I am the one who has the most favorable and trusting relationship with President Trump."
On defense cost-sharing, Kim has struck a noticeably more acquiescent tone than Lee: At a meeting Monday of the American Chamber of Commerce in Korea, he said that he would be willing to accept a hike in Seoul's contribution.
"The global order and trade environment is rapidly changing. In order to overcome these crises, it is critical that we strengthen positive cooperation and the U.S.-South Korea alliance," he said. "I will establish common ground between the two countries through comprehensive negotiations and find a win-win solution for both."
Lee Jun-seok
Polling around 10%, the 40-year old candidate from the conservative Reform Party faces long odds for the presidency.
Still, he has emphatically rejected repeated calls to form a unity ticket, presenting himself as the younger, shrewder and less doctrine-driven alternative to what he has criticized as the old-hat conservatism of those such as Kim.
At the debate Sunday, Lee Jun-seok called for "careful calculation" in navigating the U.S.-South Korea relationship under Trump, while emphasizing the need to demonstrate that South Korea is not just a trading partner but also an important strategic ally to Washington.
Yet when it comes to tariffs, he has also openly called Trump's bluff.
"I think we have to bet on the fact that Trump will eventually find that it's difficult to maintain this situation," he said on a YouTube political talk show last month, citing the economic pressures that tariffs against China will create for Trump's heartland supporters.
"What Trump is advancing isn't sustainable…. My view is that, it's likely that Trump will admit defeat as soon as within the next six months."
