The United States and ASEAN concluded the U.S.-ASEAN Trade and Investment Arrangement (TIFA) in 2006 and since then have been working to build U.S.-ASEAN trade and investment ties as well as promote ASEAN regional economic integration. The United States intensified its work under the TIFA in 2009, presenting ASEAN senior officials a number of ambitious proposals to be pursued under the TIFA work plan. These proposed initiatives seek to achieve concrete results in a variety of areas including trade facilitation, logistics, digital economy, trade finance, and trade and environment.
