What measures have been taken to develop border areas?

After the founding of the Republic of China, people have long been concerned about the problem of emigrating to and developing the frontier, and the local government in the frontier has also taken many measures. In the early years of the Republic of China, after Sun Yat-sen resigned as interim president, he actively advocated the construction of railways, seaports and immigration frontiers, especially proposed to immigrate to Xinjiang and Mongolia, and encouraged them to reclaim and cultivate land by means of loans. During the War of Resistance against Japanese Aggression period, in view of the Japanese occupation of the eastern coastal areas and massive population migration, many people suggested that the National Government emigrate to the northwest to reclaim wasteland and develop the frontier. After the victory of the Anti-Japanese War, some people still suggested organizing reclamation in the frontier. For example, in May 1947, it was suggested that the central government should allocate funds to set up large-scale collective farms in Hetao area, allocate new farm tools, improve agricultural production methods and increase grain output.
