According to the Defense Ministry, a Chinese spy balloon has been sighted over the United States.
He was spotted over the state of Montana, the BBC reported.
President Joe Biden is aware of the incident.
Pentagon spokesman and Brigadier General Patrick Ryder said the spy balloon, which is flying at an altitude above that of passenger planes, is certain to belong to China, according to the BBC.
The trajectory of the balloon is closely monitored.
He flew over Alaska and Canada before being spotted over Montana.
Considerations about a possible launch were discarded because the resulting debris on the ground could cause too much damage.
It is currently being checked whether the spy balloon poses a threat and whether appropriate countermeasures are necessary.
The incident comes just days before US Secretary of State Antony Blinken is expected in China.
