The objective of this volume is to examine international and regional preferential trade agreements that offer like-minded countries a possible way to continue to reap the benefits of economic liberalization and expanded trade. What are the strengths and weaknesses of these agreements and how can they sustain the growth and prosperity of their members in a constantly challenging global economic environment? For decades, international trade has been at the heart of economic growth and the improvement of the living standards of nations and regions of the world. For most developed countries, trade has raised living standards, while in most emerging countries, growth has only begun with their integration into the global economy. The economic explanation is simple: international trade facilitates specialization, improving efficiency, and improving productivity to an extent impossible in closed economies. However, in recent years, world trade has slowed down considerably and the global system is increasingly under attack by politicians on both the right and the left. The benefits of open markets, continued international cooperation and the benefits of multilateral institutions such as the World Trade Organization (WTO), the International Monetary Fund and the World Bank have been questioned. While globalization has had a largely positive impact on global well-being, it has also been perceived by public opinion as harmful to communities and social classes in the industrialized world, causing for example Brexit and the exit of the United States from the Trans-Pacific Partnership. .
