The Trade and Technology Council (TTC) is a transatlantic political body which serves as a diplomatic forum to coordinate technology and trade policy between the United States and European Union. It is composed of ten working groups, each focusing on specific policy areas. The formation of the TTC was first announced by US President Joe Biden and the European Commission President Ursula von der Leyen on June 15, 2021. The early agenda focused primarily on US-EU cooperation in technology, strategic sectors, market access, trade, democratic values and rule of law in the digital world, supply chain resilience, the global trade order and the EU's developing regulatory agenda like Digital Services Act, Data Act and Cloud Rules. The TTC was established under the leadership of five co-chairs – European Commission Executive Vice-President Margrethe Vestager, European Commission Executive Vice-President Valdis Dombrovskis, US Secretary of State Antony Blinken, US Secretary of Commerce Gina Raimondo, and US Trade Representative Katherine Tai.

Katherine Chi Tai is an American attorney serving as the 19th United States Trade Representative since March 18, 2021. The daughter of Chinese (waishengren) immigrants from Taiwan, she is the first Asian American to serve in the position. A member of the Democratic Party, she previously served as the chief trade counsel for the United States House Committee on Ways and Means.
