G2 Summit in Hangzhou in 216 was held in Hangzhou from September 4th to 5th, 216.

G2 Summit is an international economic cooperation forum, which was established in Berlin, Germany on December 16th, 1999. It belongs to a mechanism of informal dialogue within the framework of the Bretton Woods system, and consists of the former G8 and the other 12 important economies.

It aims to promote open and constructive discussion and research on substantive issues between industrialized developed countries and emerging market countries, so as to seek cooperation and promote international financial stability and sustained economic growth. In accordance with past practice, the International Monetary Fund and the World Bank attended the meetings of the organization as nonvoting delegates.

the G2 operates in the form of an informal ministerial meeting, with no permanent secretariat and a rotating chairman. The group's finance ministers and central bank governors meet once a year. The annual ministerial meeting is generally connected with the meeting of finance ministers of the Group of Seven, which is usually held at the end of each year. The meeting is provided with secretarial services and support by the presidency, some international institutions and external experts, and working groups can be set up as needed to review some major issues and put forward countermeasures and suggestions.

G2 Summit is hosted by G2, and its members include: G8 member countries: the United States, Japan, Germany, France, Britain, Italy, Canada and Russia, as an entity, the European Union and Australia, China, and widely representative developing countries: South Africa, Argentina, Brazil, India, Indonesia, Mexico, Saudi Arabia, South Korea and Turkey.

In order to ensure the close ties between the G2 and the Bretton Woods institutions, the Managing Director of the International Monetary Fund and the President of the World Bank, as well as the chairmen of the International Monetary and Financial Committee and the Development Committee, also participated in the activities of the forum as invited representatives.
