In the past 70 years of existence, the Soviet Union had torn up bilateral and multilateral agreements many times. Let’s make a simple and incomplete summary:
In March 1918, the newly born Soviet Union signed the Brest Treaty with Germany. The treaty stipulated that the Soviet Union would ced a total of 1.26 million square kilometers of land and a population of 62 million (equivalent to 34% of the national population), and would still have to pay 6 billion marks of compensation, which would be paid before the end of 1918. Germany was defeated on November 11 of the same year. The Soviet Union immediately announced the abolition of the treaty on November 13, and at the same time sent troops to recover the land and ceded the reparations, even more so.
1920, the Tartu Peace Treaty signed by Estonia and the Soviet Union. However, after the outbreak of , Estonia was occupied by Germany. In August 1940, the Soviet Union not only took back its previous territory on the grounds of liberating Estonia, but also turned Estonia into a Soviet republic. After Estonia became independent again in 1991, Russia did not restore the borders of the two countries stipulated in the Tartu Peace Treaty.
On July 12, 1920, Lithuanian and the Soviet Union concluded a peace treaty, also known as the Moscow Peace Treaty. The purpose of the Soviet Union signing this treaty was to exchange for Lithuania to take neutrality in the Soviet-Polish war . The peace treaty stipulates that the Soviet Union recognizes Lithuania's independence in exchange for Lithuania to allow Soviet troops to operate freely within Lithuania. This treaty is an important milestone in the international recognition of Lithuania's independence. The treaty also delineated the eastern borders of Lithuania and the Soviet Union. In the early stages of World War II in 1940, the Soviet Union breached the contract and occupied Lithuania and incorporated it into the Soviet Union.
On August 11, 1920, Latvia signed a peace treaty with the Soviet Union, also known as Riga Peace Treaty . With the signing of this treaty, the Latvian War of Independence ended. Article 2 of the Treaty stipulates that the Soviet Union will always recognize Latvia's independence in the future. In the early days of World War II in 1940, the Soviet Union also occupied Latvia and incorporated it into the Soviet Union.
On March 18, 1921, Polish signed a Riga contract with the Soviet Union in Riga, Latvia. The contract stipulates that Western Ukraine and Western Belarus and part of Lithuania will be assigned to Poland. In 1939, when Hitler attacked Poland, the Soviet Union announced that the government no longer existed due to Poland's collapse before Germany's attack, so the Riga contract was no longer necessary, so it immediately sent the Soviet Red Army to cross the border, attack Poland, and reoccupies the above-mentioned territory.
1920 and 1932, Finland -Soviet Russia signed treaties twice. The Tartu Peace Treaty was a peace treaty signed between the Soviet Union and Finland on October 14, 1920, which determined the borders between Finland and the Soviet Union. In 1932, the Soviet Union signed the "Soviet-Finns Non-aggression Treaty" with Finland. From November 1939 to March 1940, the Soviet Union mobilized one million troops to launch an attack on neighboring Finland. Although Finland resisted tenaciously, the primary school was weak and was finally forced to sign the " Moscow Peace Agreement " to cede a large area of territory.
In 1935, the Soviet Union and France signed the " Soviet-France Mutual Assistance Treaty ", which stipulates that if the Soviet Union or France is subject to unreasonable attacks by a European country, France and the Soviet Union will immediately provide assistance and support to each other. In 1940, Hitler attacked France, and France was destroyed in one month, and the Soviet Union did not provide any assistance or support.
In 1935, Czechoslovakia also signed a mutual aid treaty with the Soviet Union, and its basic content is the same as that of the Soviet-France mutual aid treaty. Similarly, when Hitler annexed Czech , the Soviet Union also made a wall view.
On April 25, 1941, while China was carrying out a arduous and outstanding war of resistance against Japan, the Soviet Union and Japan signed the " Soviet-Japan Neutral Treaty ", which stipulates that the validity period is five years. The treaty declares that the other party should remain neutral in the act of war between the other party and the third party. The Soviet Union also expressed respect for the territorial integrity and inviolability of the puppet Manchukuo (the Soviet Union is one of the few countries in the world that recognize the puppet Manchukuo), and Japan expressed respect for the territorial integrity and inviolability of the Mongolian . This treaty is actually a mutual confirmation treaty between the Soviet Union and Japan on the invasion of Northeast China and Mongolia. After the signing of the treaty, the Soviet Union stopped its anti-Japanese aid to China, and China fell into the most difficult stage of anti-Japanese resistance without any foreign aid until the outbreak of the Pearl Harbor incident and the United States publicly aided China after declaring war on Japan.
On 8th, 1945, when the five-year treaty of the Soviet-Japan Neutral Treaty had not yet expired, according to the international situation, 1.5 million Soviet Red Army sent troops to the northeast of our country, quickly defeated the Japanese Kwantung Army, liberated the entire Northeast and North Korea, and occupied part of Inner Mongolia.
On August 14, 1945, the Republic of China and the Soviet Union signed a Sino-Soviet Friendship Treaty. At that time, the Soviet Red Army had occupied part of our country's northeast and Inner Mongolia. In fact, it had controlled the Outer Mongolia for more than 4 years and was also supporting the military separatist regime in Xinjiang. In the face of the strong Stalin and under the pressure of the United States, the helpless Kuomintang government chose the "one north for two norths" plan, that is, to recognize Outer Mongolia's independence under the premise that the Soviet Union promised to ensure the sovereignty of the Northeast and Xinjiang. A few days before the signing of this humiliating treaty, Song Ziwen , who participated in the entire negotiation process, refused to sign and resigned from the post of Foreign Minister . The treaty was signed by the new Foreign Minister Wang Shijie and the Soviet People's Foreign Affairs People's Commissar Molotov .
In 1950, the Soviet Union and the New China signed the Sino-Soviet Friendship and Mutual Aid Alliance Treaty. In July 1960, within one month, the Soviet Union withdrew all 1,390 Soviet experts in China, tore up the 12 agreements signed by the Sino-Soviet government and more than 300 expert contracts, and abolished more than 200 scientific and technological cooperation projects.
