China on Wednesday rejected U.S. allegations that it conducted a nuclear explosive test in 2020, calling the claim baseless and politically motivated, according to statements reported from a Geneva disarmament forum.
U.S. Undersecretary of State Thomas DiNanno alleged that China carried out a yield-producing test on June 22, 2020, and attempted to conceal it. He offered no public evidence or location details.
Beijing denied the charge, with Foreign Ministry spokesman Lin Jian accusing Washington of distorting China’s nuclear policy to justify reviving its own testing program.

The dispute comes days after the expiration of the New START treaty between the United States and Russia, the last remaining nuclear arms control pact.
President Donald Trump has previously criticized the agreement and signaled openness to renewed U.S. nuclear testing while urging a broader deal that includes China.
According to the Stockholm International Peace Research Institute, the U.S., Russia, and China maintain significant nuclear arsenals.
