However, the Imperial Japanese Army General Staff authorized the deployment of an infantry division from the Chosen Army, two independent combined brigades from the Kwantung Army and an air regiment as reinforcements. This deployment was rescinded on 11 July on news that negotiations were being held by the commander of the Japanese Northern China Area Army and the Chinese 29th Route Army on location, and with Japanese diplomats at the Chinese capital of Nanjing. However, even after General Song Zheyuan, Commander of the 29th Army and head of the Hebei-Chahar Political Council, was reported to have come to terms on 18 July, the Japanese Army pushed forward the deployment of reinforcements citing lack of sincerity on part of the Chinese central government.
