Members of the Group of 20 leading economies ended their summit Wednesday with a declaration of firm condemnation of the war in Ukraine and a warning that the conflict is making an already delicate world economy worse.

The summit’s closing statement was noteworthy because world leaders managed to highlight a denunciation of the war despite the divisions among the group, which includes not only Russia but also countries such as China and India that have significant trade ties with Moscow and have stopped short of outright criticism of the war.

“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 statement said.

The use of the words “most members” was a telling sign of the divisions, as was an acknowledgement that “there were other views and different assessments” and that the G-20 is “not the forum to resolve security issues.”

Even so, the statement’s use of language from a March U.N. resolution that deplored “in the strongest terms the aggression by the Russian Federation against Ukraine” and demanded “its complete and unconditional withdrawal” from Ukrainian territory was a “big breakthrough,” according to John Kirton, director of the G20 Research Group.

“Here the G-20 left no doubt about who it knew had started the war and how it should end,” he said in an interview. He noted an “active shift” by China and India, which joined the “democratic side of the great immediate geopolitical divide.”

The conflict in Ukraine loomed large over the two-day summit held on the tropical island of Bali in Indonesia.

News early Wednesday of an explosion that rocked eastern Poland prompted U.S. President Joe Biden to hastily arrange an emergency meeting with G-7 and NATO members gathered at the summit.

Poland said the blast near the Ukrainian border was caused by a Russian-made missile and that it was investigating what happened. The NATO member stopped short of blaming Russia for the incident, which killed two people. Russia denied involvement.

Biden said it was “unlikely” that the missile was fired from Russia, and he pledged support for Poland’s investigation.

“There is preliminary information that contests that,” Biden told reporters when asked if the missile had been fired from Russia. “It is unlikely in the lines of the trajectory that it was fired from Russia, but we’ll see.”

Biden was joined at the G-20 by leaders including Chinese President Xi Jinping, Indian Prime Minister Narendra Modi and new British Prime Minister Rishi Sunak. Russian President Vladimir Putin did not attend.

On Tuesday, Russia pounded Ukrainian cities with dozens of missile strikes in its biggest barrage yet on the country’s energy facilities, which have been repeatedly struck as winter approaches.

Sunak, speaking to reporters at the close of the meeting, called the attacks “the cruel and unrelenting reality of Putin’s war.”

“While all world leaders were working together to tackle the greatest challenges our people face, Putin was launching indiscriminate attacks on civilians in Ukraine,” Sunak said.
