I'd suggest that it is not treaties that lead to good trans-national relations. TTIP, CETA, and the WTO treaty are examples of modern controversial treaties and treaties historically have been viewed as a very negative outcome for one of the nations.

What leads to good trans-national relations? Open borders. Because when the people of the two nations can visit, live, work, stay, build a house, settle down with a spouse and enjoy life in either country, the countries have a very hard time becoming hostile to one another.

That then leads to a completely separate question about the loss of cultural diversity, but I will not go there.

I only suggest that strong nations with open borders become friends.
