The G20 invites guest countries and international organisations to participate in its meetings and summits.
Each year the G20 president invites several guest countries to participate in G20 events and contribute to the agenda. G20 members engage with guest countries and other non-member countries  to ensure the G20 reflects a broad range of international opinion.Â
The work of G20 members is supported by several international organisations that provide policy advice. The G20 also regularly engages with non-government sectors. Engagement groups from business (B20), civil society (C20), labour (L20), think tanks (T20) and youth (Y20) are holding major events during the year, the outcomes of which will contribute to the deliberations of G20 leaders.
