The term "Caspian States" refers to the five countries that border the Caspian Sea: Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. These nations share a unique geopolitical and economic relationship due to their proximity to the sea, which is the largest enclosed inland body of water in the world. The Caspian Sea is rich in natural resources, including oil and natural gas, making it a significant area for energy production and transportation. The Caspian States have engaged in various cooperative efforts to manage their shared resources and address environmental concerns. They have established agreements to regulate fishing, protect the marine environment, and develop energy infrastructure. The collaboration among these countries is crucial for ensuring sustainable development and stability in the region.
