President Yoon Suk-yeol / Yonhap

President Yoon Suk-yeol said Thursday that under no circumstance will violence be allowed in an ongoing nationwide strike by cargo truckers.

Thousands of unionized truckers have been on strike since Tuesday to demand solutions to their rising costs amid soaring fuel prices.

"Things that can be resolved through dialogue will have to be resolved," Yoon told reporters as he arrived at the presidential office, referring to talks led by the transport ministry.

"But under no circumstance will people accept violent actions that break the law in a law-governed country," he said.
