China widened its dispute with the United States on Monday, claiming that U.S. high-altitude balloons had flown over its airspace without permission more than 10 times since the beginning of 2022. Washington called that a surveillance balloon, while China has insisted it was a weather-monitoring craft blown badly off course. A White House spokeswoman denied it, and accused China of violating the sovereignty of the United States and more than 40 other countries across five continents with surveillance balloons linked to its military. "It has repeatedly and wrongly claimed the surveillance balloon it sent over the United States was a weather balloon and to this day has failed to offer any credible explanations for its intrusion into our airspace and the airspace of others."
