Book excerpt: The globalized world has witnessed the development of a number of economic integration projects, including at least two Eurasian projects: the Eurasian Union and the Belt and Road Initiative. These initiatives blur the European Union Global Strategy adjusted in 2016 to be an attempt to reconsider and enhance the role and place of the European Union as the leader in the global arena. These initiatives must be studied and considered further to understand the numerous benefits, opportunities, and challenges they face. Regional Economic Integration and Global Competition in the Post-COVID-19 Era: European Union, Eurasian Economic Union, and the Belt and Road Initiative provides insight into the reasons and consequences of the discrepancy in the legal restrictions, institutional policies, and mutual skepticism on the economic integration progress. The text is also useful in defining and promoting a regional strategy of economic integration and the creation of mutual trust. Covering a range of topics such as international trade, environmental risk management, and globalization, this reference work is ideal for policymakers, government officials, strategic decision makers, practitioners, researchers, scholars, academicians, instructors, and students.
