South Korean President Lee Jae Myung said Thursday that the country is working hard to strike a trade deal with the United States on impending tariffs but expressed uncertainty about when talks would be concluded.

South Korea's President Lee Jae-myung is one month into the mammoth task of uniting a nation still reeling from a period of political chaos and economic uncertainty.

The approval rate of South Korea’s President Lee Jae Myung has surged to 65%, as he began his second month in office since being elected on June 3. A Gallup Korea survey of 1,001 people, carried out on the first three days of July, showed 65% of respondents backing the “good job” done by 61-year-old Lee.
