On May 22, 1933, Chinese and Japanese representatives met to talk the end of the fight. The Japanese demands were serious: a demilitarized zone covering one hundred kilometers south of the Great Wall, from Beijing to Tianjin was to be set up, with the Great Wall itself under Japanese control. No regular Kuomintang military units were to be allowed in the zone, although the Japanese were allowed to use scout aircraft or ground patrols to check that the agreement was maintained. Public order within the zone was to be maintained by a police unit Demilitarized Zone Peace Preservation Corps. Furthermore, they forced China to recognise Manchukuo as a legitimate government.
