TOKYO (Kyodo) -- China has admitted that one of its military planes entered Japan's airspace in August but said it was unintentional and vowed to take measures to prevent similar incidents from happening again, Japanese government officials said Tuesday.
The Japanese government, despite China's explanation, maintains that the Aug. 26 incident involving the Chinese military Y-9 spy plane was an airspace breach that was "a grave violation" of the nation's sovereignty, they said.
