According to reports from Newsweek, a senior official in the US administration has disclosed further information regarding a purported nuclear experiment conducted by China in 2020. This revelation has reignited debates among major nuclear powers and spurred discussions within Washington about potentially revisiting the unilateral moratorium on nuclear energy release tests, particularly if evidence of similar activities by other strategic states were to emerge. The implications of this could alter the landscape of international nuclear relations.

The situation refers back to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which was signed in 1996 by the United States, China, and Russia, prohibiting any nuclear explosions for military purposes, whether conducted on the surface, underground, or in space. Although the treaty has never formally come into effect due to the lack of ratification by key nations, it has resulted in a de facto moratorium that has largely been respected for over two decades. The current allegations could potentially threaten this established equilibrium as nations reassess their nuclear strategies.

As tensions rise, the credibility of nuclear agreements and treaties may come into question, especially as nations evaluate their security and defense policies in response to perceived threats. If Washington were to reconsider its stance on the testing moratorium, it could lead to a new arms race or provoke further hostilities among nuclear-armed states, drawing attention to the precarious nature of international nuclear diplomacy in the current geopolitical climate.
