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.
