"It will be an opportunity to further solidify the combined defense posture and operate extended deterrence between the two countries in a more concrete manner, while deepening economic security cooperation," deputy national security adviser, Kim Tae-hyo, told a briefing.

Yoon will hold a summit and a joint news conference with Biden on April 26 and deliver a speech to the US Congress on April 27 before travelling to Boston where he is due to speak at the Harvard Kennedy School, Kim said.
