The 12th round of negotiations for the Transatlantic Trade and Investment Partnership (TTIP) unfolded this week in Brussels between the EU and their American counterparts. At a time when both parties are stuck with weak growth (and persistent high unemployment in Europe), the importance of TTIP cannot be understated. When the deal is reached, it will govern the ties between combined $35 trillion dollar economies, with $5.5 trillion in commerce every year that generates up to 15 million jobs on both sides of the Atlantic. In terms of Foreign Direct Investment (FDI), the US and the EU are each other’s primary destination. Even in the wake of rising investment to and from China, it pales when compared to accumulated stocks of transatlantic FDI, as can be seen in the graphic.
