These countries of all sizes have their own territorial scope, and will form their own unique territorial form, demarcating the territorial scope of a certain country through borders.

There are nearly 200 countries in the world today. These countries of all sizes have their own territorial scope, and will form their own unique territorial form, demarcating the territorial scope of a certain country through border lines. For example, China has a territory of 9.6 million square kilometers and a long and winding border line. The total length of our border line exceeds more than 20,000 kilometers. In the end, our country's territory is like a singing rooster.

North and south polarized Vietnam

The border between the country and the country is a comprehensive result of the dual factors of natural geography and human geography, and it is also a accumulation of history and culture. Of course, natural factors still have a great impact on the direction of the border. For example, the border between my country and South Asian countries is divided by Himalayas , and there is also the existence of the north-south Andes on the west side of South America. This formed Chile, the world's longest narrowest country, on the west side of the mountain range. In addition, there is also a country with a narrow and narrow distribution of land in the Indochina Peninsula in Southeast Asia, that is Vietnam.

Vietnam's land morphology is largely due to the influence of terrain. Since the overall terrain characteristics of the Indochina Peninsula are "mountain and river intersect, and north-south column distribution", Vietnam is located on the eastern coast of the Indochina Peninsula, and the terrain is as follows: It is high in the west and low in the east. The west is mainly the north-south Changshan Mountains , extending more than 1,000 kilometers from north to south. The eastern coast is distributed with narrow plains. Therefore, in ancient times, the lives and exchanges of people in Vietnam were all north-south oriented plains. Mainly active, rarely crossing mountains to the west, and eventually forming a narrow and narrow form of the country.

Indochina Peninsula Topographic Map

To be precise, Vietnam's territory is very similar to a "dumbbell", that is, the middle is thin, north and south and ends are thick. In the northern part of Vietnam, it has a larger Red River Delta with an area of ​​about 15,000 square kilometers. The capital of Vietnam, , Hanoi, is located in the Red River Delta; in the southern part of Vietnam, there is also a larger Mekong Delta (also known as the Kowloon River Plain), and the largest city in Vietnam, , Ho Chi Minh City, is located in the Mekong Delta, with an area of ​​about 3.5 Ten thousand square kilometers. These two plain areas are the densest populous areas in Vietnam, with concentrated cities and developed industry and agriculture.

The Red River Delta region in northern Vietnam and the Mekong Delta region in southern Vietnam are connected by a narrow and long land thousands of kilometers away, so it is very inconvenient to travel. Therefore, in the development process of Vietnam, there was a long pattern of polarization between the north and the south. After World War II, due to the complex international relations and the balance of interests of all parties, Vietnam had , North Vietnam, and North Vietnam, and Mekong, as the center, under the balance of interests. , South Vietnam each develops. Later, in the Vietnam War in the 1970s, North Vietnam finally defeated South Vietnam and unified Vietnam, and established a socialist country.

Hanoi City

After the Vietnam War, although Vietnam was unified north and south, the country's development pattern was still polarized by the north and south. With their respective central cities, Hanoi and Ho Chi Minh City ( Saigon City ) as the core, it radiates and drives the Red River Delta and The development of the Mekong Delta region is still difficult to eliminate the development trend of polarization. If we want to solve Vietnam's polarization problem between the north and the south, the best solution is to integrate into China's Belt and Road strategy. The northern region of Vietnam can directly integrate into my country's Beibu Gulf Economic Circle.

Ho Chi Minh City

And the southern part of Vietnam is located at the southern end of the Indochina Peninsula and is far away. The distance between Hanoi and Ho Chi Minh City is more than 1,700 kilometers. How can we make up for this space distance? The best way is to use our country's high-speed rail technology to build a high-speed rail. It only takes 5 hours to reach it after completion. Currently, the transportation time between the two cities exceeds more than 20 hours. Through my country's high-speed rail technology and integrating into China's large market with more than 1.3 billion people, Vietnam's economy will surely develop rapidly in the integration of north and south.

Of course, the above analysis is just our assumption. In fact, Vietnam has its own small abacus. On the one hand, Vietnam has always been a vassal state of China in history. If we cooperate in depth with China, will it become an affiliate again? Where is the country? On the other hand, Vietnam and our country still have territorial and territorial waters disputes on the islands and reefs in the South China Sea, and in reality they do not want to be controlled by others. So will Vietnam eventually choose China or Japan to cooperate in infrastructure construction such as high-speed rail? Of course, Vietnam may implement the "distance and close attack" strategy, but Vietnam's failure to catch the "high-speed train" of China's great rejuvenation may be its biggest loss.
