World leaders will state that today’s era “must not be of war” and will condemn threats to use nuclear weapons at the G20 summit in Bali, reflecting rising global anxiety around Russia’s war against Ukraine.A draft communiqué agreed by diplomats, seen by the Financial Times and confirmed by two delegations, said: “Most members strongly condemned the war in Ukraine and stressed it is causing immense human suffering and exacerbating existing fragilities in the global economy.”

The language regarding the war and Moscow’s repeated use of nuclear rhetoric is stronger than western officials forecast, and underscores rising anxiety in non-western states about Vladimir Putin’s invasion and its widespread effects.

Xi Jinping, China’s president and Putin’s most important global ally, said in his speech to other leaders that the G20 “must resolutely oppose the attempt to politicise food and energy issues or use them as tools and weapons”, in some of his strongest language on the war’s fallout.
