Japanese officials said Wednesday they are closely watching to see if China keeps its promise to prevent further violations of Japan's airspace after explaining that an incursion by a Chinese military aircraft nearly three months ago was unintentional and caused by turbulence.
Tokyo protested and sought an explanation from Beijing after a Chinese Y-9 reconnaissance plane briefly entered Japanese airspace off the southern main island of Kyushu on Aug. 26, prompting Japan's military to scramble fighter jets and warn the plane.
