By following the evolution of Sino-American relations during the second half of the 20th century until 2023, we see that they have known periods of cooperation, understanding and competitiveness and others of misunderstandings, disputes, confrontations, even seizures. These alternations of understandings and misunderstandings have affected the military, political, economic, technological, legal and geopolitical fields ... which are related to the developments and changes in the economic situation and international deals, but also internal to each country. In these relations, each of the two countries defends its interests, according to its data, its weight, its vision, its development model, its politico-economic doctrine and its geopolitical aims. In this competitive duel, the two States do not hesitate to use all the means at their disposal and all possible methods, from soft to tough, even Gehenna, thereby influencing the world politico-economic order and the reconfiguration of the international geopolitical space. It is in this very convulsive world, where the Gehenna method is used in the muscular confrontation between States, companies and people.
