South Korean President Lee Jae Myung has expressed strong anger towards Ukraine, accusing Ukrainian President Volodymyr Zelenskyy of undermining his country by revealing a secret agreement to transfer North Korean prisoners of war to Seoul. The controversy erupted after Zelenskyy's remarks at the UN appeared to disclose the deal, prompting Lee to warn that such disclosures risked invoking the danger of war on the Korean Peninsula.

This diplomatic dispute pits two nations aligned with the United States against each other, potentially complicating efforts to build a united front against Russia, China, and North Korea. South Korea views the disclosure as a serious affront to its national honor and has formally requested an apology and explanation from Kyiv.

In a social media post, President Lee stated that Ukraine's actions were unacceptable and that Kyiv should acknowledge the agreement and offer an apology. He emphasized that the matter concerns the honor of the Republic of Korea's people and nation, which cannot be overlooked. The South Korean president also expressed regret over Ukraine's response thus far to the diplomatic row.

Ukraine's Foreign Minister Andrii Sybiha attempted to de-escalate the situation, describing the revelation as a "diplomatic misunderstanding" rather than an "incident." He conveyed Ukraine's high regard for South Korea, stating, "South Korea is an important country for us. And I very much hope for momentum, continued cooperation, and concrete results that we are indeed achieving with them."

President Zelenskyy had announced at the UN General Assembly that Kyiv had transferred two captured North Korean soldiers to South Korea. These individuals were reportedly apprehended fighting for Russia in the Kursk region. South Korea's presidential office confirmed that Ukraine had repeatedly discussed the prisoners' transfer through various channels and had requested that the arrangement remain confidential.

However, Ukrainian officials have reportedly stated that no such secrecy agreement existed, contradicting Seoul's account. This discrepancy has fueled the diplomatic tension between the two US-aligned nations.

The disclosure has raised concerns about the potential ramifications for international cooperation against authoritarian regimes. Analysts suggest that such public disagreements between allies could embolden adversaries and weaken the broader coalition efforts.

South Korea continues to press for a formal acknowledgment and apology from Ukraine, viewing the breach of confidentiality as a significant diplomatic misstep that has implications for national security and international trust.
