South Korea says relations with Cuba would send 'political and psychological blow' to North Korea

South Korea's presidential office said that establishing diplomatic relations with Cuba would deliver a "political and psychological blow" to North Korea.

With authoritarian leader Kim Jong Un embracing the idea of a "new Cold War," North Korea has recently been boosting the visibility of its ties with Russia and China in an effort to break out of isolation and join a united front against Washington amid tensions over its nuclear weapons ambitions. North Korean state media has yet to comment on the South Korea-Cuba agreement.
