Headline misrepresents what their acting President said. From their own article:
“After the devastation of the Korean war . . . the United States gave us aid, technology transfer, investments and security assurances,” which helped make South Korea “a very comfortable investment environment for foreigners”, Han told the Financial Times in an interview.
“Our industrial prowess and our financial development and our culture and growth and wealth are very heavily due to the help from the United States,” he added.
In light of this debt of gratitude, Seoul — one of Washington’s closest security allies and economic partners in Asia — would enter negotiations with Trump seeking to find “solutions which are more win-win for both, rather than taking their actions as the objective against which we should fight back”, Han said.
It's very that. So much so that the person who wrote the headline obviously knew exactly what they were doing.
