Evidence

The claim as worded is generic and does not specify which allegation is at issue, making precise verification difficult. Searches turned up several distinct instances of China publicly rejecting U.S. allegations, the most relevant to an active conflict being a mid-September 2026 story reported by outlets including Malay Mail and Daily Post (citing a Wall Street Journal report) in which Beijing rejected as 'groundless' claims that Chinese entities supplied Iran with satellite images of a U.S. military base in Jordan before and after a strike that killed three American soldiers. In that coverage, China's Foreign Ministry called the allegations baseless, but none of the retrieved sources explicitly quote Beijing as 'demanding Washington produce evidence to support the claim' — that specific phrasing was not found verbatim in any outlet. Other similar but unrelated China-U.S. denial stories were also found (e.g., tariff evasion accusations, AI allegations, voter-records claims, election interference claims), none of which match the 'active conflict' framing as closely as the Iran/Jordan base story. No fact-check from Reuters, AFP, Bellingcat, or EUvsDisinfo specifically addressing this exact quote or claim was located.
