During the Ming Dynasty, why were there no western regions in the territory?

The Western Regions were not included in the territory of the Ming Dynasty because the cost performance of the Western Regions had been greatly reduced at that time, and the state was unwilling to invest a lot of manpower and material resources here, so it adopted a laissez-faire policy.

The prosperity of the Western Regions was only seen in the Han and Tang Dynasties, because it was an important way of the Silk Road on land, and businessmen from all over the world came and went here, which promoted the economic development and prosperity. Therefore, both the Han and Tang Dynasties actively strengthened their control over the Western Regions, and the wealth gathered here made the court have to pay attention to it.

The Song Dynasty lost control of the western regions because of its weak national strength, so it increased the development of the southeast coastal areas, and the Maritime Silk Road began to flourish, replacing the original economic status of the western regions. This also led to the gradual collapse of economic and trade activities in the western regions, which lost the driving role of the Central Plains Dynasty. The market development in the western regions also collapsed rapidly and suffered from war. Until the establishment of the original western regions in the Ming Dynasty, there was no bustling scene.

After the establishment of the Ming Dynasty, it attacked the adherents entrenched in Mobei for many times. However, the problems left by the Yuan Dynasty were too serious, so it was not visited to the west for the time being. Moreover, due to the geographical environment, the western regions were not cultivated with agriculture and had no original commercial value, which became very tasteless. It took a lot of national strength to capture this land, and it was also a huge consumption, which easily caused the original Islamic forces in the western regions to rebound.

The Hexi Corridor and Hetao area, which have the most strategic value in the Western Region, were incorporated into the territory by the Ming Dynasty, which has taken away the essence of the Western Region, and there is no need to spend more energy on the remaining waste land. During the Qing Dynasty, the western regions were brought into the territory again because of Zhungeer's rebellion, which led to an honest expedition to occupy this piece of land with little value. Influenced by the internal and external factors at that time, the Ming Dynasty gave up the actual rule of the western regions without the threat of forces that actually affected the state rule.
