1, weak foundation:
Vietnam is a big agricultural country, not an industrial country. It has no complete development system. Before the Vietnam War, Vietnam didn't even have a decent city, and its only advantage was the title of coastal city. However, Vietnam lacks its own resources, and no one wants to attract investment. Those who wanted to come were rejected by the Vietnamese, which eventually led to the withdrawal of enterprises.
2. miss the golden period of development perfectly:
Since 1960, the world has entered the third era of scientific and technological revolution. Although Vietnam 1986 has only developed, it is still possible to seize the opportunity to order some soup. Japan, South Korea, Singapore and other countries have developed in this way.
However, there was still a war in Vietnam at that time, and the government had no intention of development at all. If the Soviet Union had not intervened, the internal contradictions would not have subsided. Therefore, on the whole, it makes sense that Vietnam is still poor. However, with the development of demographic dividend and tourism, Vietnam has made good progress in recent years.
