Russian diplomat calls Australian threat of physical confrontation with Putin 'immature'

A Russian diplomat has dismissed the Australian prime minister's threat of a physical confrontation with the Russian president as immature, warning that Vladimir Putin is a judo expert.

Prime Minister Tony Abbott told reporters on Monday he was "going to shirtfront Mr. Putin" at an international summit next month, using an Australian Rules Football term for a head-on shoulder charge to an opponent's chest aimed at knocking the opponent backward to the ground.

Alexander Odoevski, third secretary of the Russian Embassy in Canberra, told Australian Associated Press Abbott's threat was "tough talk" and "immature."

Abbott on Tuesday did not directly answer questions about whether he would carry through with the threat or regretted making it.

But he says he is "absolutely determined to have a very robust conversation" with Putin.
