Fan called on Myanmar to seriously investigate the incident, and urged the Myanmar side to severely punish the perpetrators, as well as apologize to and  compensate the families of the victims. He voiced hope that the Myanmar side would settle the incident well and work with China to ensure the safety and stability of the border areas. Min Aung Hlaing said the Myanmar side understood China's feelings and assured that the Myanmar side would send personnel to jointly investigate the incident with the Chinese side. Min Aung Hlaing also promised to properly handle relevant issues and hold relevant people accountable. He said the Myanmar military would advance friendly cooperation with the Chinese army.Myanmar's warplanes have on several occasions crossed the China-Myanmar border and stray fire has caused casualties and loss of property of the Chinese people, Fan said.
