Norwegian perspective

In line with Norway's emphasis on inclusive international processes, the United Nations, and the UN system, in a 2010 interview with Der Spiegel, the current prime minister of Norway Jonas Gahr Støre called the G20 "one of the greatest setbacks since World War II" as 173 states who are all members of the UN are not among the G20. This includes Norway, a major developed economy and the seventh-largest contributor to UN international development programs, which is not a member state of the EU, and thus is not represented in the G20 even indirectly. Norway, like other such states, has little or no voice within the group. Støre argued that the G20 undermines the legitimacy of international organizations set up in the aftermath of World War II, such as the IMF, World Bank and United Nations:

The G20 is a self-appointed group. Its composition is determined by the major countries and powers. It may be more representative than the G7 or the G8, in which only the richest countries are represented, but it is still arbitrary. We no longer live in the 19th century, a time when the major powers met and redrew the map of the world. No one needs a new Congress of Vienna.

However, Norway, has moderated this position in practice, and has contributed to a number of G20-work streams for years, in particular on health, energy and climate. Under the government of Erna Solberg, Norway attended the 2017 G20 summit in Hamburg, Germany.
