Both Eastern partnership and the Union for the Mediterranean (UfM) are American creations, they say, to actually restrain economic pace of American major economic rivals in the region. The then president of France Sarcozy said upon the establishment of UfM that it would "build peace in the Mediterranean together like we built peace in Europe" in framework of the EU, Eastern Partnership including.

Formally, the new grouping is to deal with environmental challenges, immigration, security cooperation, transport and education. But it's plain clear it's going to be just like in case of the EU which leadership is playing under American tune now.
Now, Europeans should thank Washington not for peace in Europe but for the Ukrainian war and the anti-Russian sanctions having most devastating effect on the EU countries' economies and security! We should expect similar things in the UfM too, I guess!
