On 1945, Jiang Jingguo went to the Soviet Union to negotiate and sign the Sino-Soviet Treaty of Friendship and Alliance.
Stalin asked: "Why do you insist on not letting Mongolia' independence'?" Jiang Jingguo said that China insisted on the war of resistance in order to recover lost territory. Today, Japan did not drive away, but ceded a piece of land as big as Mongolia. Didn't it lose the original intention of the war of resistance? People will never forgive the government of the Republic of China and will say that they sold their land. The government of the Republic of China cannot agree to Stalin's independence from Mongolia. "
Stalin said, "Your words are very reasonable. I'm not ignorant. But, you know, today I don't want you to help me, but you want me to help. If your country has the strength to fight Japan alone, I will naturally not ask for it. Today, if you don't have this right, it's nonsense to say these things! "
After several months of diplomatic struggle, Jiang Jingguo's father, General Chiang Kai-shek, insisted on a bottom line: "It must be pointed out that Mongolia needs a referendum." This was added in the Sino-Soviet Treaty.
Finally, under the bayonet of the Soviet Red Army, Stalin held a referendum in Mongolia, and everyone was personally monitored for real-name voting, which meant that it would be difficult to save lives against the occupiers. As a result, Mongolia became independent.
Mongolia covers an area of nearly10.6 million square kilometers, which is equivalent to three France. As an ally and victorious country of Stalin, China lost 3 12 times more territory than the defeated Japanese, which is also the largest loss of territory since the early Qing Dynasty to the Republic of China.
