Mr Putin arrived at Brisbane International Airport on Friday night just after 9:10pm (AEST), travelling on an Ilyushin Il-96-300PU Russian airliner.
In an interview with Russia’s state news agency TASS before he left for Australia, Mr Putin said economic sanctions imposed over the Ukraine crisis were “harmful”.
“The fact that certain countries of the G20 are imposing sanctions on Russia through the G20, of course, this contradicts the very principle of the G20’s activity,” he said.
Mr Putin added that the sanctions not only ran counter to the principles of the G20, but were against international law.
“This also contradicts international law because sanctions can only be imposed through the United Nations and its Security Council,” he said.
But Mr Putin said he would not raise the topic of sanctions at the G20.
“Why should I draw attention to this, ask for something? It’s pointless.”
