Yul's statements strain relations between Moscow and Seoul. South Korean Foreign Ministry files complaints about Moscow's criticism of North Korea's pursuit of a nuclear arsenal.

Russian Foreign Ministry described Yul's comments as "blatantly biased" Washington and its allies see Russian President Vladimir Putin as strengthening ties with Pyongyang since the invasion of Ukraine in 2022. The U.S. and allies have condemned what they say are large shipments of North Korean missiles to Russia to aid its efforts to develop nuclear weapons.
