China is refusing to let US secretary of state Antony Blinken visit Beijing over concerns that the FBI will release the results of an investigation into the downed suspected Chinese spy balloon.
Four people familiar with the negotiations said China had told the US it was not prepared to reschedule a trip that Blinken cancelled in February while it remains unclear what the administration of president Joe Biden will do with the report.
The FBI has been analysing debris salvaged from the balloon since it was shot down in February. The US says the craft was spying on sensitive military sites, but China say it was a weather balloon blown off course by weather.
