Reuters news agency reported that fighter jets and maritime patrol aircraft from South Korea and Japan, as well as the US aircraft carrier USS George Washington, will participate in the "Freedom Edge" exercise from November 13.

The exercise also includes maritime missile defense training and cyber defense training, according to the South Korean Joint Chiefs of Staff (JCS).

The drills come as the US State Department says North Korean troops have begun taking part in combat operations in Russia's military campaign in Ukraine.

Japan's Kyodo news agency on November 12 quoted a senior Ukrainian government official as saying that there are currently about 50,000 Russian and North Korean soldiers deployed to the Kursk region and are fighting against Ukrainian forces.

As Russia and North Korea tighten cooperation, on the same day, Secretary General of the South Korean Peaceful Unification Advisory Council Tae Yong-ho commented that Pyongyang will not dialogue with Washington during this time.

According to him, North Korea is currently focusing on relations with Russia and Chairman Kim Jong Un may return to relations with China after the conflict in Ukraine ends.

Secretary-General Tae Yong-ho called on the US administration to make clear that the goal of denuclearizing the Korean Peninsula is a top priority and cannot be compromised.
