The chairman of the United States Joint Chief of Staff will visit South Korea to check the South Korea-U.S. combined defense posture.

The South Korean military Friday said that Marine General Joseph Dunford will arrive on Sunday from Japan to meet with Seoul’s top defense officials including his South Korean counterpart Lee Sun-jin and Defense Minister Song Young-moo.

The U.S. JCS chief will reportedly pay a courtesy visit to President Moon Jae-in during his two day trip to Seoul.

Dunford’s trip, which is part of his Northeast Asia tour, draws attention as it comes amid North Korea’s threats of attack against the United States and South Korea.

Dunford will reportedly visit China after his trip to Seoul.
