A more thorough explanation:

International economic law is a branch of international law that deals with the economic relations between countries and private parties involved in cross-border economic and business transactions. It includes:

• International trade law
• Law of international financial institutions (or international financial law)
• Private international law fields
• Regional Economic Integration, such as the European Union, ASEAN and other regional trade organizations
• International law and development
• International commercial arbitration
• International intellectual property law
• International business regulation

For example, international trade law deals with the rules and regulations that govern the exchange of goods and services between countries. The World Trade Organization (WTO) is an international organization that oversees and regulates international trade. Another example is international intellectual property law, which deals with the protection of intellectual property rights, such as patents, trademarks, and copyrights, in cross-border transactions.

Overall, international economic law plays a crucial role in promoting economic growth and development, as well as ensuring fair and equitable economic relations between countries and private parties.
