This text investigates how international law functions as a foundational framework for the global political and economic system while balancing state sovereignty against collective international obligations. Vaughan Lowe, a recognized scholar in the field, utilizes a conceptual approach to examine the tension between the independence of states and the constraints imposed by human rights, environmental standards, and global economic integration. The book argues that international law is not merely a set of static rules but a dynamic mechanism for distributing power and authority among sovereign entities.
