More than 10 such incidents dealt with responsibly, professionally since last year
China said on Monday that high-altitude balloons from the United States had flown over its airspace more than 10 times since the beginning of last year without permission from Chinese authorities.
"It is not an uncommon thing for US balloons to illegally enter other countries' airspace," Foreign Ministry spokesman Wang Wenbin said, noting that China has dealt with the US balloons in a responsible and professional way.
