bound

SEOUL, May 7 (UPI) — North Korea is not bound by the global treaty aimed at preventing the spread of nuclear weapons, its U.N. envoy said Thursday, calling efforts to force Pyongyang to comply with the pact a “wanton violation” of international law.

Kim Song, North Korea’s permanent representative to the United Nations, made the remarks in a statement carried by the state-run Korea Central News Agency during an ongoing review conference of the Nuclear Non-Proliferation Treaty at U.N. headquarters in New York.

The United States and other countries at the conference are “groundlessly taking issue with the present status and exercise of sovereign rights of the Democratic People’s Republic of Korea, a nuclear weapons state outside the treaty,” Kim wrote, using North Korea’s official name.

“The position of the DPRK as a nuclear weapons state does not change in accordance with rhetorical assertion or unilateral desire of outsiders,” he said. “Clarifying once again, the DPRK is not bound by the NPT in any case.”

North Korea formally withdrew from the NPT in 2003 and in 2022 passed a law declaring itself a nuclear state. Leader Kim Jong Un later called the country’s nuclear status “irreversible,” and Pyongyang amended its constitution to codify the expansion of its nuclear forces.

Pyongyang has repeated the assertion frequently, including during a rare address to the U.N. General Assembly in September, when a senior diplomat vowed the North would “never give up” its nuclear weapons.

In a 2025 report, the Stockholm International Peace Research Institute estimated that North Korea possesses about 50 nuclear warheads and has enough fissile material for about 40 more. South Korean President Lee Jae Myung said in January that North Korea was producing enough weapons-grade material to build between 10 and 20 nuclear weapons annually.

The envoy’s statement comes ahead of U.S. President Donald Trump’s visit to China next week, where speculation has persisted that the trip could provide an opportunity to revive leader-to-leader diplomacy with Kim Jong Un.

Trump held a pair of high-profile summits with Kim during his first term in office and has suggested on several occasions that he would meet with the North Korean leader again.

Kim appeared to leave the door open to renewed diplomacy with Washington in remarks last year, saying he retained “fond memories” of Trump but warning that denuclearization was off the table.

On Monday, a White House official told Yonhap News Agency that a Trump-Kim meeting was “not currently on the schedule.”

Pyongyang says its status as nuclear-armed state ‘will not change based on external rhetorical claims’.

North Korea’s envoy to the United Nations has declared that Pyongyang will not be bound by any treaty on atomic weapons and that no external pressure will change its status as a nuclear-armed state.

Ambassador Kim Song’s statement – carried by state media on Thursday – came as the United States and other countries criticised North Korea’s nuclear programme at the ongoing UN conference reviewing the Nuclear Non-Proliferation Treaty (NPT).

Pyongyang withdrew from the NPT in 2003 and has since conducted six nuclear tests, promoting multiple UN Security Council sanctions.

The country is believed to hold dozens of nuclear warheads.

“At the 11th NPT Review Conference currently under way at UN headquarters, the United States and certain countries following its lead are groundlessly calling into question the current status and exercise of sovereign rights,” Kim said, according to the official Korean Central News Agency.

“The status of the Democratic People’s Republic of Korea as a nuclear-armed state will not change based on external rhetorical claims or unilateral desires,” he added.

“To make it clear once again, the Democratic People’s Republic of Korea will not be bound by the Non-Proliferation Treaty under any circumstances whatsoever.”

He continued that the country’s status as a nuclear-armed state has been “enshrined in the constitution, transparently declaring the principles of nuclear weapons use”.

North Korea has long insisted that it will not give up its nuclear arsenal, describing its path as “irreversible” and pledging to strengthen its capabilities.

It has sent ground troops and artillery shells to support Russia’s invasion of Ukraine, and observers say Pyongyang is receiving military technology assistance from Moscow in return.

The nine nuclear-armed states – Russia, the US, France, the United Kingdom, China, India, Pakistan, Israel and North Korea – possessed 12,241 nuclear warheads in January 2025, the Stockholm International Peace Research Institute (SIPRI) reported.

The US and Russia hold nearly 90 percent of nuclear weapons globally and have carried out major programmes to modernise them in recent years, according to SIPRI.

The nuclear issue has been at the heart of the US and Israel’s war on Iran, with US President Donald Trump saying that Tehran – a signatory to the NPT – can never have a nuclear weapon.

Iran denies seeking an atomic weapon and has long demanded Washington acknowledge its right to enrich uranium.
