Interstate cooperation refers to the collaboration between different states or regions to address common challenges and achieve shared goals. This can involve working together on issues like environmental protection, public health, or economic development. By pooling resources and expertise, states can create more effective solutions than they could individually. Such cooperation often takes place through agreements, treaties, or organizations that facilitate communication and joint action. For example, states might form a regional alliance to tackle climate change or improve infrastructure. This teamwork helps build stronger relationships and fosters a sense of community among states, benefiting everyone involved.
