Russia's president has praised the Australian government for its "welcoming atmosphere" at the G20.

Russian President Vladimir Putin has praised the Australian government for the atmosphere at the G20 summit in Brisbane.

"(Our) Australian partners created an extraordinarily welcoming atmosphere for work. I was surprised by the warmth with which normal Australian citizens received our delegation," Putin told a forum of supporters in Moscow, according to an official transcript on Tuesday.

Putin also added praise for Prime Minister Tony Abbott.

Putin's comments defied media reports that the Russian president was so frustrated at being sidelined and subjected to tough talk by Western leaders that he left the summit early.
