The assessments of global summits seem to be measured by new minimum standards, given the current state of international cooperation: The G20 concluded its summit in Buenos Aires on 1 December 2019 without any significant ruptures and with a joint declaration. This outcome was all but self-evident, after President Trump withdrew his consent to the communiqué of the last G7 Summit in Charlevoix, Canada, via Twitter while flying back to Washington. And at the recent APEC summit, the US and China clashed over trade issues and the meeting ended without a joint declaration – usually a diplomatic given. The recent intensification of the tensions between Russia and Ukraine as well as the international outcry against the killing of the Saudi government’s critic Jamal Khashoggi added to the challenges. G20 summitry watchers were therefore all but certain that the Buenos Aires summit could be concluded in an orderly fashion. It is a success for the Argentinian host that it did despite all the headwind.
In Buenos Aires on 30 November and 1 December 2018, the G20 is having its 10th anniversary as a summit format at the leaders’ level. On 14 and 15 November 2008, this previously-obscure group of finance ministers and central bankers of the nineteen most “systemically relevant” countries and the EU was transformed into a forum for international leaders to meet with a view into the abyss of the global financial crisis that originated in the US and spread fast across the world. Ten years and 12 leaders’ summits later, the G20 has moved beyond its 2008-09 role as a crisis-management forum and became the self-described “premier forum for […] international economic cooperation.” In this capacity it is now facing new demands to tackle global challenges such as climate change, digitalization and pandemics. As its agenda has expanded and the urgency of the crisis fades, the G20 faces questions regarding its relationship to other formal institutions of global governance, such as the United Nations, its effectiveness in dealing with global challenges as well as its legitimacy and accountability vis-à-vis its people and the 174 non-members.
The G7 Summit on 8 and 9 June 2018 in Charlevoix, Canada, ended in the worst possible outcome. Even an open clash at the negotiation table would have been better than President Trump’s post-summit withdrawal from the joint communique. On his road of destruction of the existing international order, Donald Trump has deprived the G7 of its operating principle: the forging of shared purpose as a basis of joint action among a select group of important countries. This is a bad omen for the upcoming G20 Summit in Buenos Aires, Argentina, at the end of the year.
