Cyprus and Lebanon signed an important agreement about the sea between them. They signed it on Wednesday in Beirut. The agreement took almost twenty years to make. It says where each country can use the sea for things like finding gas and oil.
Turkey and the Turkish Cypriot leader do not like this agreement. They say it is not fair. They say the Greek Cypriot government cannot make decisions for the whole island of Cyprus. They want the international community to reject the agreement.
But the President of Cyprus, Nikos Christodoulides, says the agreement is very good. He says it ends twenty years of no agreement. It will help with future energy projects. He also invited Turkey to talk about the sea boundaries directly.
Experts say this agreement changes the situation in the region. It helps Lebanon's weak economy with possible energy projects. The European Union also promised Lebanon 500 million euros in support. This agreement is important for energy in the Eastern Mediterranean, but it also causes more diplomatic problems.
