SEOUL — South Korean President Yoon Suk Yeol will travel to Washington next week for a NATO summit, where he is expected to sound the alarm on Russia and North Korea's recent military cooperation, his administration announced on Friday.

Yoon's deputy national security adviser Kim Tae-hyo said NATO members and the so-called Indo-Pacific 4 — Korea, Japan, Australia and New Zealand — would 'confirm their shared commitment to protecting the international order... in the face of the challenges' seen in both the eastern and western hemispheres.
