Look at the map showing the european union (eu) and countries with which it has free-trade agreements (ftas). which is the reason the eu had free-trade agreements with almost every country on the mediterranean sea

The reason is to create a deep European Mediterranean Free Trade Area. Its goal is to remove barriers to trade and investment between the EU and Southern Mediterranean countries ( with the exception of Syria and Libia ) and to create a peaceful environment for fair trading and economic prosperity. Due to regional differences and political situation in the countries involved this process is not considered to be easy, these countries have one of the lowest level of regional economic integration in the world. The EU is keen to offer help to strengthen the economic bond there by means of free trade and fair economic competition which is done with help of FTAs.
