With the arrival of US President Donald Trump to the White House, on January 20, the year witnessed a remarkable escalation in international trade tensions, raising questions about the outbreak of a “fourth world war” of an economic nature. I say a fourth world war, because historically the first and second world wars relied on traditional military conflicts, including the reach of the year of technology and military manufacturing at the time, including chemical and nuclear weapons, while The Cold War was characterized by diplomatic conflicts and wars by proxy between the major powers and spy battles and security and diplomatic breakthroughs, we are still following its chapters to this day, which ended with the collapse and disintegration of the Soviet Union, but today we are facing an economic confrontation that may be more profound on peoples, especially the poor and marginalized groups. It is received from China, and threatened to impose higher fees if new commercial agreements were not reached, and he announced the imposition of customs duties by 25% on imported cars, with the aim of encouraging the American industry, with expectations to collect $ 100 billion annually from these fees, these policies were not limited to China only, but also included traditional allies such as Canada, Mexico and the European Union, which led to the escalation of commercial tensions on a global scale. The procedures show a trend towards a protectionist policy aimed at restoring balance to the American trade balance, but at the same time raises fears of the outbreak of a comprehensive commercial war, the White House stressed that these fees will enter into implementation as soon as they are announced, which increases the possibility of retaliatory reactions from the commercial partners. The disturbing in this economic war is its direct impact on ordinary individuals, especially the poor who seek to secure their day’s livelihood, high Customs duties may lead to an increase in the prices of imported goods, especially food products, which weighs the shoulders of consumers, and negatively affects their purchasing power, in addition to that, developing countries that depend on export may be affected by the American markets, which increases the complexity of their economic, political and security conditions. In light of these developments, it seems that the world is coming to a new stage of economic conflicts, where commercial and economic tools have become a major weapon In achieving political goals, this transformation requires developing countries to enhance their economic capabilities and develop policies that protect their interests in facing these escalating challenges.
