G-20: Biden to press world leaders to hold tough on Russia over Ukraine war

President Joe Biden was set to try to cajole the world's largest economies to further isolate Russia diplomatically and economically over its invasion of Ukraine despite a souring global outlook that has tested other nations' resolve.

In meetings Tuesday at the Group of 20 summit in Indonesia, the U.S. leader is to continue a global tour pressing nations to stand up to Russia and defend Ukraine's sovereignty in both symbolic and substantive ways.

The effort comes as global inflation and slowing economies have put new pressures on countries that imposed penalties on Russia for the nine-month war that has sent food and energy prices soaring.

In opening the summit, Indonesian President Joko Widodo impressed on the gathering what's at stake.

If the war does not end, it will be difficult for the world to move forward, Widodo said. We should not divide the world into parts. We must not allow the world to fall into another cold war.

A senior U.S. administration official, speaking on the condition of anonymity to discuss the summit, said Tuesday that the summit's final communique will make clear that most of the nations condemn Russia's invasion in Ukraine and the toll it has taken on global food and energy supplies.

It's unclear how many nations would embrace the tough language or whether the document would refer to Russia's actions as a war a phrase Moscow has sought to avoid, despite the devastating losses sustained by its military.

The European Council president, Charles Michel, urged other global powers to intensify pressure on Russia over its war against Ukraine, including Moscow's biggest supporter, China. Michel said Tuesday that the summit was crucial to stopping Moscow's push to use food and energy as weapons."

U.S. officials have said Biden's trip has demonstrated that countries large and small are willing to condemn Russian aggression. Russian President Vladimir Putin has stayed away, sending his foreign minister, Sergey Lavrov.

The Indonesian president invited Ukrainian President Volodymyr Zelenskyy to virtually address the G-20 summit, just days after Ukraine's foreign minister was invited to participate in the Association of Southeast Asian Nations summit in Cambodia, where it became the latest signatory to the group's treaty of amity and cooperation.

Chinese officials have largely refrained from public criticism of Russia's war, although Beijing has avoided direct support of the Russians, such as supplying arms.

Biden said he and Chinese President Xi Jinping discussed Russia's aggression in a meeting Monday and reaffirmed our shared belief that the use or even the threat of nuclear weapons is totally unacceptable a reference to Moscow's thinly veiled threats to use atomic weapons as its invasion of Ukraine has faltered.

The summit schedule does not include a family photo of leaders, which would avoid a potentially awkward moment of interaction with the Russian representative, Lavrov. It remained to be seen how Biden and U.S. allies would react when Lavrov is recognised to speak during the summit's closed sessions. Some Europeans have discussed potentially walking out of the meeting to protest Russia's invasion.

U.S. national security adviser Jake Sullivan said no one in the U.S. delegation had plans to meet with Saudi Crown Prince Mohammed bin Salman, often known as MBS, after Biden accused Saudi Arabia of siding with Russia by leading the OPEC+ cartel to cut oil production last month in a bid to sustain the elevated energy prices that Russia uses to fund its war in Ukraine.

It also was not clear whether anyone from the U.S. delegation would meet with Indian Prime Minister Narendra Modi or other leaders whose cooperation is needed to secure a price cap on Russian oil to limit the profits Moscow uses to invest in its defense base.

The summit will be the first for two critical new partners in Biden's effort: British Prime Minister Rishi Sunak and Italian Premier Giorgia Meloni.

Sunak, who took office last month after the disastrously short tenure of Liz Truss, has promised to continue his conservative predecessors' steadfast support for Ukraine. He and Biden are set to strategise during their Wednesday meeting on new ways to bolster Ukraine's defenses for the long haul.

Meloni has pledged to continue to provide arms and aid for Ukraine, but questions remain over her far-right coalition's commitment to stand up to Russia. She will meet with Biden privately on Tuesday afternoon.

One leader who will be absent is Cambodian Prime Minister Hun Sen, who tested positive for COVID-19 after his arrival in Bali and said he was returning home. So far, no other leaders are known to have tested positive, though many of those in Bali also attended meetings with Hun Sen just days ago during a summit of the Association of Southeast Asian nations.
