Erm, the entire university system in Europe is built on collaboration between countries.

ESA is a thing. ITER is a thing. But mainly all those small international projects that simply would be too niche or small for a single country or market. Im talking about stuff like wave power startup, on land fishfarms, salvage operations in the baltic, cofinancing of highways (or powerlines so that green energy may find its way across the union), et cetera..
