The Advisory Board is one of the Think 20 (T20) Argentina governing bodies. The engagement group is coordinated by The Argentine Council for International Relations (CARI) and Center for the Implementation of Public Policies for Equity and Growth (CIPPEC) during this year.

Its function is to assess the T20 in relation to topics related to policy, content, media strategy, funding and public relations. This also includes the plenary sessions and the final publication of the report which the T20 will present to the G20 presidency.
