Japan protested to China on Monday about what it says are groundless accusations that Japanese fighter jets had fired “jamming shells” as six Chinese military planes flew over waters between Japan’s southern Okinawa and Miyako islands. “It is extremely regrettable that the Chinese military is making announcements that are clearly factually wrong,” Chief Cabinet Secretary Yoshihide Suga told reporters. Japan scrambled fighters on Saturday as Chinese planes flew over the Miyako Strait. Taiwan’s defense ministry said four Chinese planes also flew over the nearby Bashi Channel between Taiwan and the Philippines. The waterways and airspace are two of the connections between the contested South and East China seas and the Pacific Ocean.
