Kim Yo-jong Says North Korea’s Nuclear Status Is Irreversible After IAEA Warning

Kim Yo-jong, the influential sister of North Korean leader Kim Jong-un, has declared that Pyongyang’s status as a nuclear-armed state is irreversible, rejecting renewed calls for denuclearization from the International Atomic Energy Agency and Western governments.

Her statement, carried by North Korean state media on Thursday, followed criticism of Pyongyang’s nuclear program at the IAEA General Conference, which opened on September 14. South Korea and European countries told the meeting that the program threatens the global nuclear non-proliferation system and urged the North to comply with United Nations Security Council resolutions.

Kim dismissed the conference’s calls for complete, verifiable and irreversible denuclearization as a repetitive exercise with no bearing on North Korea’s policy. She argued that international conferences and statements could not weaken the country’s determination or its ability to take measures that it considers necessary to protect state interests.

She also said North Korea’s nuclear status had been fixed both physically and legally, asserting that rhetorical objections from countries hostile to Pyongyang could not change that reality. The comments reinforce the widening divide between North Korea and governments that continue to demand the dismantlement of its nuclear weapons program.

The statement came as the IAEA highlighted signs of continued development at North Korean nuclear facilities. In an annual report released before the conference, the agency described indications that uranium enrichment capacity was expanding and that nuclear reactor operations were continuing. Such activity has remained a central concern for international monitors because the IAEA has not had inspectors inside North Korea since 2009.

North Korea has repeatedly framed its nuclear arsenal as essential to national defense, while South Korea, the United States and other partners maintain that Pyongyang must fulfill its international obligations. The latest statement indicates that the North is not treating denuclearization as a negotiable objective, even as the issue remains embedded in international resolutions and diplomatic policy.

Kim’s intervention also gives added political weight to Pyongyang’s response. As a senior Workers’ Party official and one of the most prominent voices on external affairs, she frequently delivers statements setting out the leadership’s position toward South Korea, the United States and international organizations.

The immediate exchange does not signal a new negotiation or policy opening. Instead, it underscores a hardened standoff: international institutions continue to document and condemn North Korea’s nuclear activity, while Pyongyang increasingly presents its nuclear weapons status as permanent and beyond discussion.
