The United States accused China of conducting a secret nuclear test in 2020, an allegation that China has categorically denied. The Russia===Kremlin also denied that either Russia or China has carried out any secret nuclear tests. This development comes as the United States is pushing for a new, broader arms control treaty that would include both China and Russia, following the expiration of the New START agreement on February 5. The expiration of New START has raised concerns among some experts about a potential acceleration of the nuclear arms race, while others believe these fears are exaggerated.
