China conducted 'secret nuclear test' days after Galwan clash, says US

The US has accused China of conducting a secret nuclear explosive test in June 2020, shortly after the deadly Galwan Valley clashes. This allegation, revealed at a global disarmament forum, heightens India's strategic concerns over China's military posture amidst ongoing border tensions. China denies the claims, accusing the US of exaggerating threats and fueling an arms race.
