President Lee's X posts spark fresh diplomatic clash with Ukraine over POW disclosure

President Lee Jae Myung warned Ukraine of extra measures unless it apologizes for revealing two North Korean POWs, a dispute amplified by his X posts.

President Lee Jae Myung used his X account to condemn Ukrainian President Volodymyr Zelenskyy’s recent UN General Assembly remarks that named two North Korean prisoners of war now held in South Korea. Seoul argues the public disclosure violated a secret arrangement intended to shield the soldiers and their relatives, whereas Ukraine maintains no such pact existed. Lee labeled the announcement “very disappointing,” later warning of “additional measures” if Kyiv does not issue a public apology.

Foreign ministers from both sides have been discussing a mutually acceptable response, but analysts say Lee’s direct social-media approach complicates quiet diplomacy. The episode mirrors a prior controversy with Israel, highlighting concerns about the president’s reliance on online platforms. Lee’s posting frequency has surged, and critics note the risk of unvetted statements reaching the public.

Why it matters

The dispute shows how a leader’s social-media use can strain international relations and hinder diplomatic resolution.
