China Rebuffs New U.S. Accusation on Nuclear Test-Site Activity

China rebuffed a U.S. accusation that it had maintained activity at a nuclear weapons test site, with a foreign ministry spokesman saying the country was upholding its commitment to the international testing ban.

In a summary of an annual report assessing global arms-control agreements, the U.S. State Department said Wednesday that China “maintained a high level of activity” at its Lop Nur test site in the western region of Xinjiang. The report noted “possible preparations” to operate the site year-round and “concerns” that China wasn’t complying standards adhered to by the U.S., France and the U.K.
