Russian President Vladimir Putin at a press conference within the framework of the G20 conference in Australia.

Russian President Vladimir Putin left the Group of Developed and Emerging Economies (G20) summit in Brisbane, Australia on November 16 early because he needed enough time to sleep.

Western leaders simultaneously put pressure on the Russian President at the G20 conference.

Canadian Prime Minister Stephen Harper told Putin: `I thought I would shake your hand, but I only have one thing to say, you need to get out of Ukraine.`

A famous satirical Twitter account in Russia also called the G20 conference the `G19 + 1 Summit in Australia`, referring to Western countries isolating Russia.

`Countries do not de-escalate tensions,` Russian newspaper Gazeta.ru commented.

Mr. Putin has recently become the focus of international talks.

However, Mr. Putin’s early departure from the Brisbane conference raised tensions to a whole new level.

Fyodor Lukyanov, Chairman of the Council for Foreign and Defense Policy, an agency with close ties to the Russian government, warned that criticism from the West could prompt Mr. Putin to take a tougher stance.

`We are seeing the West increasingly radicalize its stance, first of all North America and Australia, the hosts of the conference,` Lukyanov said on radio.

`They do not wish to ease tensions. On the contrary, tensions are increasingly being exposed. Russia’s reaction is very predictable, Moscow will show a tougher stance,` he said.

Lilia Shevtsova, an analyst at the Brookings Institution, said that as Russia’s confrontation with the West becomes more serious, Moscow becomes more dependent on China.

`The Asia-Pacific Economic Cooperation (APEC) summit in Beijing and the G20 meeting in Brisbane confirmed that President Putin is `isolated,` she wrote on Facebook.

`A country is isolated and wants to rely on another country, world politics has not known a more explosive combination.`

Analysts also believe that Mr. Putin’s early departure will receive sympathy from domestic supporters.

He said Mr. Putin’s attitude will be interpreted by his supporters as `The Russian leader has nothing to say to the West.`

According to The Guardian, although Western media portrayed Mr. Putin as isolated at the conference, he continued to maintain close relations with emerging economies including Brazil, India, China and South Africa.
