US Accuses China of Secret Nuclear Test Post-Galwan Clash

• US Under Secretary of State Thomas G DiNanno alleged China conducted a secret, yield-producing nuclear explosive test in June 2020.
• The alleged test occurred just one week after the deadly Galwan Valley clash between Indian and Chinese forces.
• DiNanno claimed China used 'decoupling' to hide its activities and prepare for tests with designated yields in the hundreds of tonnes.
• The US official highlighted that the New START treaty's limits are irrelevant as China expands its arsenal unconstrained.
• China's ambassador on disarmament, Shen Jian, denied the 'false narratives' and stated Beijing handles nuclear problems responsibly.
