US balloons

China says US balloons breached airspace at least 10 times

It comes after the US on 4 February shot down a suspected spy balloon over its airspace - which China said was one of its weather balloons gone astray.

Relations between the two countries have since deteriorated. In recent days, the US has also shot down a number of other unidentified objects.

Questioned on Monday, Beijing said the US had made many airspace breaches.

"It's not uncommon as well for the US to illegally enter the airspace of other countries," said foreign ministry spokesman Wang Wenbin at a regular press briefing.
