During the negotiations, Wang Jingwei hoped to gain more "independence" to decorate the facade, but the Japanese side forced Wang to accept it completely, which led to a heated debate between the two sides and the negotiations were suspended. The negotiations lasted for two months, and the Japanese side only made a slight concession on the details. Under the coercion of Japan, Wang Jingwei was forced to sign a secret contract calling himself a "prostitution contract".
Wang Jingwei completely accepted Japan's cruel conditions in exchange for Japan's support for his organization of the traitor regime. According to the secret agreement, the Japanese obtained the political, economic and military privileges of China. As the treaty was too harsh and exposed Japanese ambition to destroy China, both sides agreed to "never publish" its contents.
Wang Ching-wei and others originally looked down on the traitor organizations established under the bayonet of the Japanese army, such as the interim government and the reform government, and thought that their reputation was too smelly and they were unwilling to cooperate with them. However, Japan insisted that the new "central government" should include all the old and new traitor regimes, and forced Wang Jingwei to start merger negotiations with them immediately. Wang Jingwei first tried to get in touch with Wu, who was wooed by Japan, but they did not agree on the connotation of "Sino-Japanese peace" and "slightly different positions". They also have their own plans for the power distribution of the new regime in the future. Wu also despised Wang's personality, showed indifference and even teased Wang. He wrote in Wang's letter inviting him to join the puppet regime: "Being away from Chongqing on business, I have no one to rely on. If the tiger comes out of the mountain and enters the clubhouse, there is no value in seeking peace! If I can go back to Chongqing. Electricity can come and go. "
Although Wu was a frustrated warlord, he didn't fall into the water as a traitor. Later, he suffered from dental diseases and died of septicemia. Later, under the arrangement of the Japanese army, Wang Jingwei began to negotiate and cooperate with Wang Kemin, Chairman of the Administrative Committee of the North China Interim Government, and Liang Hongzhi, Executive Dean of the Central China Reform Government, to establish a "central government". Wang Kemin, etc. Those who rely on themselves to take refuge in Japan refuse to submit easily first. Their "independent status" with Wang Zhengduo and their position in the future regime. After several bargaining, the "interim government" was finally changed into the "North China Autonomous Committee" with great independence, and all the important members of the "reform government" were appointed as senior officials, which came to an end. The new traitor and the old traitor finally merged.
