Cyprus and Lebanon are two countries. They are near the Mediterranean Sea. They agree where their sea border is. They sign a new paper.
They talk about this for many years. Now it is finished. The United States is happy about this news.
The agreement uses a simple line in the middle of the sea. This is a good rule. Now, both countries can work together. They can look for gas in the sea. They can keep the sea safe.
This is important for peace. Other countries in the area see this. Maybe they will make similar agreements too.
