ELI5: Explain Like I'm 5

Regional integration

Regional integration is when countries that are close together join forces to work together. It is like joining a club. They work together on things like policy, trade, and even the environment! For example, if two countries decide to join forces and do things like open a free trading area, this would be regional integration. They would be working together and helping each other out. It can also help countries develop and grow together and lead to improvements in the quality of life for everyone.
