Japan and China are blaming each other after Tokyo raised concern that a Chinese fighter jet came dangerously close to Japanese reconnaissance planes.

It has a diamond-shaped wing and no tail fin, which makes it more hidden and better at flying smoothly through the air.

China has deployed both of its aircraft carriers—CNS Liaoning and CNS Shandong —to the east of the first island chain since June 7. Japan's military reported that its patrol aircraft was intercepted by fighter jets launched from the Shandong while conducting surveillance.
