Although U.S. President Donald Trump has expressed hopes of meeting North Korean leader Kim Jong-un during his tour of Asia next week, a senior Trump administration official says no such meeting is on the schedule for the upcoming trip.

The official made the statement at an online press briefing Friday, but added that “things can change.”

Trump’s trip includes a last stop in South Korea ahead of the Asia-Pacific Economic Cooperation summit in Gyeongju.

The official’s remarks come amid speculation about a Trump-Kim meeting in the Demilitarized Zone separating the two Koreas during Trump’s two-day state visit to South Korea, which starts Wednesday after stops in Malaysia and Japan.

While in South Korea, Trump is scheduled to hold talks with President Lee Jae Myung, as well as Chinese President Xi Jinping.
