With which state in Asia did the Egyptians sign the first-ever peace treaty?

In the 13th century BC, there was a struggle between the Hittites and Egypt for the lands of Palestine and Syria. Ultimately, the Egyptians had the advantage. Thus, they were able to secure the lands of Phenicia, Palestine, as well as the territory of Damascus. So in 1270 BC, a peace treaty was concluded between the parties. The daughter of the Hittite king became the wife of the Egyptian pharaoh.
