Head of Myanmar's Presidential Office Zaw Htay cited radar and GPS records as proof that Myanmar's fighter jets did not stray into Chinese territory. He also said Yangon had always informed Beijing of its airstrikes in the border region beforehand. He also promised "full cooperation" with Beijing into the incident. Beijing strongly protested the bombing and said it had sent fighter jets to fend off further intrusion.
