Why did the Soviet troops withdraw from Northeast China in 1946?

Reasons:

1. The day before Japan announced its surrender, Wang Shijie, Minister of Foreign Affairs of the Nationalist Government, signed the "Sino-Soviet Treaty of Friendship and Alliance" with the Soviet Union in Moscow. The treaty stipulated that war Later, the sovereignty of Northeast China was transferred to the National Government;

2. The Soviet army began to withdraw within three weeks after Japan surrendered, and completed the withdrawal in three months. After the end of the Anti-Japanese War, the Nationalist Government actively prepared to take over Northeast China. On August 29, 1945, Chiang Kai-shek called Chen Cheng, Acting Secretary-General of the Supreme Council of National Defense, and proposed six measures for the recovery of the Northeastern provinces.

Explanation:

1. Hui serves as the director, with political and economic committees and the Office of the Northeastern Commissioner of the Ministry of Foreign Affairs. Chiang Ching-kuo serves as the diplomatic commissioner, and Du Yuming serves as the Northeast Security Commander. The Northeastern Administrative Region was redivided from the original three provinces into nine provinces and two cities including Liaoning and Andong;

2. In mid-October, Xiong Shihui and Du Yuming flew to the Northeast successively to start takeover negotiations with the Soviet side. Just when the Nationalist Government was preparing to take over sovereignty, the Soviet Union vigorously destroyed industrial and mining enterprise equipment in the Northeast. In early September, the Soviet army began to selectively demolish Japan's original industrial equipment, causing the largest power grid in Northeast China, the power generation capacity of the Northeast Power Plant to drop from the original 1.8 million kilowatts to 800,000 kilowatts.
