A senior US official has claimed that China secretly carried out an underground nuclear explosion in June 2020. According to the report, the US government has released new intelligence suggesting that a seismic event detected on June 22, 2020, near China’s Lop Nur test site may have been caused by a nuclear detonation. The information was disclosed by Christopher Yao, Assistant Secretary at the US State Department, during an event in Washington.

Yao stated that a remote seismic monitoring station in Kazakhstan recorded a 2.75-magnitude tremor approximately 720 kilometers from the Lop Nur site. He argued that the data did not match mining explosions or natural earthquakes and was consistent with signals expected from a nuclear test. However, the international organization responsible for detecting nuclear explosions said it lacked sufficient data to confirm Yao’s claim.

Responding to the allegation, Chinese Embassy spokesperson Liu Pengyu in Washington dismissed the accusation as baseless, calling it an attempt by the United States to justify resuming its own nuclear testing program.
