The report, which cited information from two unidentified senior officials in US President Donald Trump’s administration, said contract chipmaker SMIC “began sending the tools to Iran roughly a year ago”.
A US official was quoted in the report as saying they had “no reason to believe that any of this has stopped”.
China is a key partner of Iran but has not announced military assistance to Tehran in the war triggered by US-Israeli strikes on February 28, repeatedly calling for a ceasefire. The chipmaker, Semiconductor Manufacturing International Corporation (SMIC), did not respond to an AFP request for comment on Friday.
Asked about the report at a regular news conference in Beijing, foreign ministry spokesman Lin Jian said he was “not familiar with the situation”. “What I can tell you is that recently, some media have been keen on releasing some news that seems right but instead is wrong,” Lin said.
