South Korea and Ukraine agreed Wednesday to deepen security cooperation in response to the “threat” posed by the deployment of North Korea troops in Russia, the presidency in Seoul announced.

Axar.az reports that, citing AFP, the statement followed a meeting between South Korea’s president and Ukraine’s defense minister after their countries sounded the alarm over the deployment of thousands of Pyongyang’s troops in western Russia.

South Korean Presidenton Yo Suk Yeol met with Defense Minister Rustem Umerov and “expressed hope that South Korea and Ukraine would work together to devise effective measures to address security threats posed by North Korea’s military cooperation with Russia,” the presidency said.

“Both sides agreed to continue sharing information on North Korea’s troop deployment to Russia and the transfer of weapons and technology between Russia and North Korea,” the presidency added.

The trip came after South Korea signaled it could reverse a long-standing policy of not providing weapons to countries in conflict but there was no mention of arms supplies in the statement.
