The United States is currently negotiating two massive regional economic agreements, one with 11 Asian and Pacific Rim countries and the other with the 28-member European Union. The Trans-Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (TTIP) herald a substantial shift in US foreign economic policy as Washington turns its focus from the stalemated Doha Round of multilateral trade negotiations and scattered bilateral trade agreements to 'mega-regional' trade diplomacy. As the only party to both negotiations, Washington seeks to leverage issues in one to advance its interests in the other, while reinvigorating US global leadership.
