President Yoon Suk-yeol is set to meet with U.S. Vice President Kamala Harris in Seoul on Thursday amid an escalation of North Korea's missile testing and concern about economic repercussions from the U.S. Inflation Reduction Act (IRA).

Harris, who is traveling to South Korea from Japan, will make her first visit to the country as vice president. The last time a U.S. vice president visited South Korea was in February 2018, when Mike Pence led a delegation to the PyeongChang Winter Olympic Games.

Harris' visit comes only hours after North Korea fired two short-range ballistic missiles into the East Sea in apparent protest of an ongoing South Korea-U.S. military exercise involving an American aircraft carrier.

The North had also conducted a similar short-range ballistic missile test on Sunday.
