Japan signed the Japan Soviet Neutrality Treaty, and the whole country celebrated, why was the Sovie

The Soviet Union felt that it had one less serious rival, and the biggest opponent of the Soviet Union was Germany, and after signing a neutrality treaty with Japan, it would concentrate on dealing with Germany and avoid being flanked.

Japan signed a Sino-Soviet non-aggression pact, and the Japanese were also able to free up their hands, so they were very happy, and the Soviets also had this idea, and they were able to free up a large number of troops.

Because the Soviet Union was able to obtain the corresponding benefits, the Soviet Union was only in the final war against Japan, and the gains outweighed the losses.

Because they didn't want to fight on two fronts, the Soviet Union wanted to deal with the war on the European side, so as to avoid a two-front war, so signing such a neutrality treaty was very beneficial to him.

For the sake of its own security and its own interests, the Soviet Union was a temporary exchange of interests, but it harmed China's interests, accelerated Japan's attack on China, and relaxed Japan's hostility to the Soviet Union.

At this time, the strength of the Soviet Union could not be underestimated, and the signing of this treaty was obvious that Japan was trying to compromise.

Japan has no sincerity in implementing the Soviet-Japanese Neutrality and Friendship Agreement. The 1941 plan, codenamed "Seki-sei", was not only an attempt to seize the territory of the Soviet Far East, but also intended to use Omsk as the dividing line between fascist Germany and militarist Japan to carve up the Soviet Union. With the defeat of the fascist German army on the Soviet-German battlefield, Japan's plan to take advantage of the favorable situation on the Soviet-German battlefield to invade the Soviet Union also came to naught.

But Japan "still considered an attack on the Soviet Union to be one of the basic purposes of their policy, and neither abandoned its aggressive ambitions, nor did it abandon its preparations for an attack." Accordingly, on April 5, 1945, the Soviet Union announced the abrogation of the Soviet-Japanese neutrality agreement.

In the summer of 1940, Nazi Germany successfully blitzed the Western European continent, and Japan decided to take the opportunity to advance southward to seize the influence of Western countries in Asia and the Pacific. In order to implement the strategy of southward expansion, while strengthening its collusion with Germany and Italy, Japan actively sought to readjust its relations with the Soviet Union in order to consolidate its security in the north and urge the Soviet Union to stop aiding China and achieve the goal of ending the "China incident" at an early date. At this time, the Soviet Union, which was facing the threat of Nazi aggression, in order to get rid of the danger of being attacked by the east and the west, on the one hand, supported China's war of resistance in order to tie Japan's hands and feet; On the other hand, we will strive to sign a treaty with Japan to ensure the security of the eastern border.

Beginning in July 1940, talks between the two countries began at the initiative of Japan. Negotiations were suspended at the end of August. After the signing of the Treaty of the Axis Alliance between Germany, Italy and Japan, Japan was committed to the negotiation of the Soviet-Japanese neutrality treaty, and Japan put forward the "Japan-Soviet Non-Aggression Pact Plan".

He also appointed Army Lieutenant General Miji Kenkawa as the new ambassador to the Soviet Union to accelerate the pace of negotiations between Japan and the Soviet Union. On October 30, 1940, Jianchuan visited Molotov and submitted the "Japan-Soviet Non-Aggression Pact Plan" drafted by Japan. On November 18, 1940, the Soviet Union proposed the Draft Soviet-Japanese Neutrality Treaty and the draft Subsidiary Protocol.

Negotiations were suspended again in mid-December.
