Russian president Vladimir Putin plans to leave the G20 summit early, a member of his delegation said, after Western leaders blasted Moscow for the crisis in Ukraine and threatened more sanctions.
The Russian official told Reuters that Putin planned to skip a working session on Sunday at the two-day summit in Brisbane and bring forward his departure because he needed to attend meetings in Moscow.
The source has denied President Putin is bowing out after facing scrutiny from Western leaders over Moscow's alleged involvement in the conflict in eastern Ukraine.
Mr Putin's spokesman has told Russian radio the leader will leave the summit when all work is completed.
Russia has denied it was involved in a recent escalation of military activity in Ukraine, where fighting has claimed more than 4,000 lives, but faced strong rebukes from Western leaders, including US president Barack Obama and Canadian prime minister Stephen Harper.
"I guess I'll shake your hand but I have only one thing to say to you: you need to get out of Ukraine," Mr Harper told Mr Putin at the summit, according to his spokesman Jason MacDonald.
Mr Putin's response to the comment was not positive, Mr MacDonald said in an email, without elaborating.
Mr Obama said Russian aggression against Ukraine was a threat to the world, while the European Council demanded Moscow withdraw troops and weapons from the neighbouring nation and put pressure on rebels there to accept a ceasefire.
Mr Obama said the United States was at the forefront of "opposing Russia's aggression against Ukraine, which is a threat to the world, as we saw in the appalling shoot-down of MH17".
