Why is the outline of Egypt so flat?

The border problem in Africa is mainly the bane left by modern western colonial rule. Colonial powers usually divide the border offices of African countries according to latitude and longitude, geometric lines or lines drawn on maps by rulers. For example, part of the border between Egypt and Sudan is drawn along the 22nd parallel. According to statistics, 44% of the borders of African countries are drawn by longitude or latitude, 30% by geometric methods of straight lines or curves, and only 26% are natural borders composed of rivers, lakes or mountains. The dispute between Egypt and Sudan in Haila Ib area left over from colonial rule in the Red Sea area is nearly 65438+100000 square kilometers. At that time, the British colonial rulers took 22 degrees north latitude as the dividing line between the two countries, but they split the two local nationalities that crossed 22 degrees in two. (2) Theme: The little-known "Halaib" territorial dispute between Egypt and Sudan. When you look at the map of Africa, I wonder if you have noticed this phenomenon. The eastern border between Egypt and Sudan. One is bounded by 22 degrees north latitude, and the other is offset to the north, forming a triangular area. This area is the Haraibb Triangle, covering an area of 20,580 square kilometers, located on the coast of the Red Sea in Africa. The largest town is Halab. The sovereignty of the Halab Triangle is disputed, and both Egypt and Sudan claim sovereignty over this land. From 65438 to 0899, Britain had a strong influence in this area. The border between Egypt and Sudan was demarcated by the Anglo-Egyptian agreement according to the 22nd parallel. However, in 1902, Britain drew a separate "administrative boundary" for its own convenience, and put the triangle area north of 22 degrees north latitude under Sudan's jurisdiction. 1958, Egyptian President Nasser sent Egyptian troops into the disputed area, but he quickly withdrew. Later, the two sides shelved their claims to the area, but the land has been under the control of Sudan. 1992, another dispute occurred between the two countries, because the Sudanese government granted a Canadian oil company the right to drill oil in the waters near the Harab triangle, and Egypt expressed strong opposition. Therefore, the two sides resumed negotiations. The Canadian company has also given up this business unless the sovereignty issue is resolved. On June 5438+ 10, 2000, Sudan withdrew its troops stationed in the halab triangle and gave up control of this area near Egypt. The Egyptian army has since taken control of this area. However, Sudanese President Bashir announced in 2004 that although his country withdrew and Egypt took control of the Halab Triangle, the triangle still belongs to Sudan legally. He insisted that Sudan would never give up the city of Halaib and its surrounding areas. The newly discovered oil reserves in the region may prompt the Sudanese government to decide to claim Sudan's sovereignty over the region again, which will only increase the desire of both sides to claim sovereignty over the region.
