Vice President Harris met with South Korean President Moon Jae-in Friday, without the participation of President Biden, and then the two appeared together to make a statement.

A bilateral meeting at the White House between a U.S. vice president and a visiting head of state followed by a joint appearance featuring the two is highly unusual.

The event included a photo-op of Harris and President Moon walking and talking before the meeting, which included Moon and several of his aides, and Harris and several of hers.

Harris’ session with Moon is not the first time the vice president has spoken on her own with world leaders.

Harris also took a call with Jordanian King Abdullah II Thursday, to address the Israeli-Palestinian cease-fire in Gaza.

Since taking office in January, Harris has spoken with French President Emanuel Macron, Canadian Prime Minister Justin Trudeau and Israeli Prime Minister Benjamin Netanyahu.

Fox News could not immediately reach the White House for comment on what she and Moon discussed, but Harris said that “challenges that exist on the Korean peninsula” would be at the top of the list.
