The United States has accused China of secretly conducting a nuclear test, claiming to possess evidence that points to a low-yield nuclear explosion detected by a seismic signal near the Lop Nur site in western China in June 2020. U.S. officials assert that the recorded data does not align with any known earthquake or mining activity, suggesting the possibility of a covert test intended to evade international monitoring systems.

This accusation has re-ignited debates surrounding nuclear arms control, stirring concerns about the future of international agreements in the wake of increasing distrust between the two nations. The escalation reflects a broader trend of heightened military and strategic rivalry, with both powers engaging in competitive posturing that has significant global implications.

In response, Beijing has categorically denied the allegations, accusing Washington of manipulating facts to justify its own nuclear strategy. International experts have expressed caution, indicating that the situation requires careful monitoring to avoid miscalculations that could further exacerbate tensions in an already fraught geopolitical landscape.
