International law must be upheld, the communique says, adding that the threat of the use of nuclear weapons was inadmissible.

The declaration, approved on Wednesday after a two-day summit in Indonesia, said the majority of members strongly condemned the war in Ukraine but there were other views. There was no immediate statement from Russia.

International law must be upheld, the communique said, adding that the threat of the use of nuclear weapons was inadmissible. It welcomed the Black Sea grain initiative as the war has prevented much-needed grain to world markets.

“Many members… expressed concern about the damage caused by the conflict on critical health infrastructure, as well as casualties in health care workers, which have disproportionately affected the most vulnerable, women and children,” said the communique.

The war on Ukraine was hurting the global economy, it said. The declaration also said members’ central banks would continue to calibrate the pace of monetary policy tightening.

UN Secretary-General Antonio Guterres, also in Bali for the summit, warned it was “absolutely essential to avoid escalating the war in Ukraine”.

His comments came after an explosion in Poland, a NATO member, which immediately sparked concerns the alliance might be drawn directly into Russia’s nearly nine-month war against Western-backed Ukraine.

Leaders also agreed to pursue efforts to limit the rise in global temperatures to 1.5 degrees C (2.7 degrees F), including speeding up efforts to “phase down” the unabated use of coal.

“This will require meaningful and effective actions and commitment by all countries,” the declaration said.
