Russia attends G20 meeting set to be dominated by Ukraine crisis

Russian Foreign Minister Sergei Lavrov has flown into Indonesia's resort island of Bali for a meeting of G20 foreign ministers, which is set to be overshadowed by tensions triggered by the Russia-Ukraine conflict.

The G20 gathering runs until Friday in host country Indonesia, which this year has grappled with the balancing act of running a global summit buffeted by geopolitical pressures and a global food crisis blamed on the conflict.

There was tight security on Thursday in Bali's Nusa Dua area, where the summit is being held, as foreign diplomats descended on the tropical island for the meeting.

Speaking ahead of her arrival in Bali, German Foreign Minister Annalena Baerbock said Russia must not be allowed to use the G20 meeting as a platform given its conflict in Ukraine.

"It is in the interest of us all to ensure that international law is respected and adhered to. That is the common denominator," Baerbock said in a statement.

The summit will see the first face-to-face meeting between President Vladimir Putin's long-serving foreign minister Lavrov and some of Russia's biggest critics since the attack on Ukraine, which Moscow has called a "special military operation".

Lavrov had arrived in Bali and planned to meet some G20 counterparts on the sidelines of the summit, Russian news agency TASS reported, but ministers including Baerbock and US Secretary of State Antony Blinken have ruled out meeting Lavrov.

The Group of 20 includes Western countries that have accused Moscow of war crimes in Ukraine and rolled out sanctions, but also countries like China, Indonesia, India and South Africa that have been more muted in their response.

Discussions on energy and food security are on the agenda in the two-day meeting, with Russia accused of stoking a global food crisis and worsening inflation by blockading shipments of Ukrainian grain. Russia has said it is ready to facilitate unhindered exports of grain.
