(MENAFN) US President Donald Trump’s move to restart nuclear weapons testing signals a worsening international crisis and threatens the global framework for security and peace, according to Rafael Grossi, the director general of the International Atomic Energy Agency (IAEA).

In an interview with a TV channel on Tuesday, Grossi characterized Trump’s decision as a “manifestation of profound unease, tension, and increasing fragmentation,” warning that it erodes both worldwide peace and the non-proliferation system.

Last week, Trump instructed the US Department of War to begin preparations for nuclear trials, arguing that the United States is “the only country that doesn’t test” and accusing Russia and China of conducting “secret” nuclear detonations. Both Moscow and Beijing have denied these accusations.

Grossi raised doubts about the accuracy of Trump’s statements, highlighting that any nuclear explosions by other nations would be detected by the international surveillance network established under the Comprehensive Nuclear-Test-Ban Treaty.

The IAEA chief stressed that the organization tasked with monitoring compliance “can immediately record such phenomena.”

He urged for a renewed role of the United Nations in promoting global stability and protecting the nuclear non-proliferation framework amid escalating tensions.

Kremlin spokesperson Dmitry Peskov has so far avoided commenting directly on Trump’s remarks, noting that Moscow is waiting for “clarifications from the American side.”

He emphasized that neither Russia nor China has resumed nuclear testing and that both remain committed to their obligations under the Comprehensive Nuclear-Test-Ban Treaty.
