Trade policy has become the essence of the economic recovery and adjustment in the post-pandemic period on a global level. The COVID-19 pandemic has caused a series of disruptions in the international trade, prompting countries to redefine their approaches to meet new challenges. This thesis analyzes changes and trends in trade policy since the pandemic and explores how countries have adapted their strategies to ensure stability and sustainability. The paper explores various aspects of trade policy, like the role, the instruments, the goals, and the tasks; a review of the history, principles, and structure of the World Trade Organization; an analysis of the COVID-19 pandemic; and the reaction of the World Health Organization, as well as a review of trade policy in the post-pandemic period. Analyzing examples of protectionist measures and trade agreements, the paper indicates the advantages and challenges brought by each strategy of protectionist measures. The post-pandemic period remains as relevant as the virus itself. Wartime relations between Ukraine and Russia have made this challenging period even more difficult, and international relations are more tense than ever before. The conclusions point to the need for a balance between the protection of domestic interests and the maintenance of open markets and for emphasizing multilateral cooperation in order to overcome trade misunderstandings and reduce political tensions. The post-pandemic period is an opportunity to promote innovation and diversification and to ensure a fair trade framework that will ensure the stability, growth, and prosperity of the global economy. Through an analysis of trade policy in the post-pandemic period, this paper is contributing to a better understanding of the dynamics of trade, its impact on the future, and the necessity of economic cooperation.
