This chapter examines legal frameworks that help nations conduct business across borders. It studies how both legally binding and non-binding regulations influence how states and global actors behave in international business. Globalization connects national economies by allowing businesses to trade and invest across countries. It is not simply about removing borders, globalization affects product creation and consumption patterns while introducing new business practices globally. Businesses now function across borders as financial markets respond quickly globally, while customers can buy from international sources. The digital age makes commerce easy but produces legal challenges that no single country can solve alone. When globalization works well, it needs a solid legal system to keep it transparent and open for everyone. The lack of laws would turn global markets into gaps where unfair business practices and uncontrolled money movements create economic problems.
