The content of the transaction is that Jordan exchanges 7,000 square kilometers of land for 6,000 square kilometers of land in Saudi Arabia plus 19 kilometers of coastline. Not Jordan. Only 19 kilometers of coastline and 7,000 square kilometers of land. Because a normal person knows 7000 square kilometers of land, 19 kilometers of coastline, buying heavy and buying light, so there are 6000 square kilometers of land to exchange. Although Jordan and Saudi Arabia exchanged those deserts for these land areas, they were all barren, just like the Gobi Desert in China.
When Jordan was founded, its coastline was only seven kilometers long. Later, they exchanged 19 kilometers of coastline, and their coastal coastline was only 26 kilometers long. Maybe they have their own considerations, such as marine resources, fish and shrimp resources, land resources, and some oil and gas resources on the seabed. Although they may not have thought so much about it in the last century, now the ocean has territorial rights, and it is considered as the territory of this country within 300 nautical miles, so it is more profitable to go to Jordan for this activity.
Because the 6000 square kilometers they exchanged, or 7000 square kilometers, were empty. No resources. If there were resources, they would have been exploited long ago. Now in Saudi Arabia, they earn foreign exchange mainly by exporting resources. It may be said that some resource areas are in the exchange area, but not many. Then Jordan also got some coastline and ocean resources it wanted, so it was a win-win situation acceptable to both sides.
