There is EU / Schengen which immensely boosted local economies. We had TTIP but unfortunately it was killed by opposing forces, and there is still MERCOSUR. However, Germany with it's brilliantly corrupt leadership, changed that strategy to "trade facilitates change" ("wandel durch handel") and went all in to removing trade barriers w/ russia and china because the idea was to convince them if we trade they won't try to kill us. Obviously this approach failed. Strategically, it does not make sense for democratic countries to have higher trade barriers with each other than with autocrat states. But over time the hybrid warfare by autocrat states leveraged social media to convice people to vote against their own interest e.g. brexit.
