China suspends spy balloon program after U.S. shootdown

China has suspended its surveillance balloon program after one balloon crossed into U.S. airspace and was shot down.
The U.S. believes the balloon's entry was unintentional and has reprimanded the operators.
China aims to improve relations with the U.S. before a potential Biden-Xi meeting.
The U.S. widened radar systems after the incident to better detect objects in its airspace.
The program suspension is an attempt to ease tensions following the February shootdown incident.
