The Group of Twenty (G20) comprises 20 major advanced and emerging economies (19 countries plus the European Union). The first G20 Summit was held in Washington in November 2008, and was convened by the US in response to the emerging financial crisis then. Subsequent G20 Summits have been held in London (April 2009), Pittsburgh (September 2009), Toronto (June 2010), Seoul (November 2010), Cannes (November 2011), Los Cabos (June 2012), St Petersburg (September 2013), Brisbane (November 2014), Antalya (November 2015), Hangzhou (September 2016), Hamburg (July 2017), and Buenos Aires (December 2018).
Singapore, although not a G20 member, has been invited to participate in the G20 Summits and its related processes in 2010 to 2011 and from 2013 to 2019. Singapore has usually been invited as a representative of the Global Governance Group (3G). The 3G is an informal grouping of 30 small and medium-sized countries, which aims to promote greater transparency and inclusivity in the G20 process by encouraging stronger linkages between the G20 and the broader UN membership.
Japan holds the 2019 G20 Presidency, and seeks to promote a free and open, inclusive and sustainable, “human-centered future society”. Prime Minister Lee Hsien Loong will participate in the G20 Osaka Summit from 28 to 29 June 2019. Japan will also host eight G20 Ministerial Meetings this year, including the G20 Foreign Ministers Meeting in Nagoya from 22 to 23 November 2019.
