日本占领东北后,义军的反抗接连不断,马占山等退入俄境后,1933年出现了华东共和国的抗日政权,制定了《约法》,发表了《告民众书》、《告各国书》。在致巴比塞调查团的公函中阐述了东北的现状和共和国的使命。东北是可以早日光复的,只因南京政府的错误内外政策,使日本在东北统治了14年。 After Japan occupied the northeast, the rebel resistance continued one after another. After Ma Zhanshan and other returned to Russia, the anti-Japanese regime of the East China Republic emerged in 1933, and the “Covenant on Law” was drafted. In his letter to the Barbican mission, he elaborated on the status quo in the Northeast and the mission of the Republic. The Northeast can be reconstituted as soon as possible, only because of the wrong internal and external policies of the Nanjing government, which ruled Japan for 14 years in the northeast.
