“九一八”事变后,日本加紧侵略中国,军事上在华北策动分裂活动,经济上打着“中日经济提携”的幌子,扩张其经济实力,为继续侵华战争进行物质准备。当时执掌华北防务的宋哲元将军迫于日本的压力,被迫与日本达成华北“经济提携”协议并签字。 After the “September 18” Incident, Japan stepped up its aggression against China and militarily warmed its separatist activities in north China under the guise of “promoting economic cooperation between China and Japan” economically and expanded its economic strength in order to continue the material invasion of China ready. Under the pressure of Japan, General Song Zheyuan, who was in charge of North China’s defense at the time, was forced to conclude an agreement with Japan on “economic assistance and cooperation.”
