President Yoon Suk-yeol plans to speak by phone with visiting U.S. House Speaker Nancy Pelosi later Thursday, his office said, after officials said earlier that a meeting between the two is not planned as Yoon is on summer vacation.

Pelosi arrived in Seoul on Wednesday night amid heightened tensions between the United States and China in the wake of her visit to Taiwan. China denounced Pelosi's trip and announced live-fire military drills around Taiwan in protest.
