PRESSURE is growing on Russian President Vladimir Putin at the G20 Summit as western countries up the ante over the conflict in Ukraine. European leaders will meet their American counterparts in Brisbane on Saturday - and all are growing increasingly impatient with Russia. Tougher sanctions will be considered as soon as Monday. European Council President Herman Van Rompuy said while the escalating situation in Ukraine was not on the G20 agenda, it would will be high on the list when European leaders meet United States president Barack Obama on Saturday. Russian President Vladimir Putin. And the EU members will meet on Monday to consider greater diplomatic pressure on Russia, including greater economic sanctions. "We will continue to use all diplomatic tools including sanctions at our disposal," von Rompuy told reporters. The EU foreign ministers will on Monday assess the situation on the ground and discuss possible further steps. "We need to avoid a return to a full-scale conflict," he added. He called for both side to abide by the cease-fire agreement between Ukraine and the rebels that was signed in Minsk, Belarus, in September. The conflict has already killed 4000 people and Ukraine has accused Moscow of sending more troops and weapons to support a new offensive by pro-Russian separatists. Russia must use its influence on the rebels to ensure they comply with the Minsk agreement, stop the flow of weapons and troops from Russia and withdraw Russian troops already in Ukraine, von Rompuy said. "Russian for its part must apply all its influence on rebels to ensure the implementation of the Minsk agreements," Van Rompuy told a media conference. Russia must stop the inflow of weapons and troops from its territory into Ukraine and Russia must withdraw those already present. U.S. Secretary of State John Kerry reflected the European mood. The State Department said Kerry expressed "grave concern" about increased Russian support for the separatists and called for the implementation of the Minsk agreement, including a cease-fire, border monitoring, release of all hostages and a return to dialogue during a discussion with Russian Foreign Minister Sergey Lavrov. It follows an incredible public attack by Australian Prime Minister Tony Abbott hours before Mr Putin landed in Brisbane late Friday.

Russia has faced sanctions around the world following the annexation of Crimea in March, as well as continued troop movements near eastern Ukraine. Australian Federation of Ukrainian Organizations spokeswoman Irene Stawiski said their protest would call for the G20 nations for stronger sanctions against against Russia.

Russian media claim Mr Putin says he has no plans to raise trade sanctions - imposed by countries including Australia following the MH17 disaster - at the G20 forum as he thinks it would be "useless." But Mr Putin has told Russian state news agency TASS the G20 nations which had imposed sanctions had made a "mistake" that had hurt not just Russia, but the global economy. "If this theme is mentioned, I shall speak on the subject, of course, but I am not going to propose these questions for discussion myself," Mr Putin is quoted as saying. The way I see it, it will be useless. All understand what they are doing. Those who impose the sanctions. What's the use of drawing attention to this matter or asking for something? It'll make no sense. "Such decisions are made at the level of blocs and at the national level, they are made on the basis of our partners" understanding of their geopolitical interests. I believe that's just a mistake, even from the standpoint of their geopolitical interests. This is harmful and, of course, it does certain damage to us, but it is also harmful to the United States, because as a matter of fact the entire system of international economic relations is being undermined. I do hope, and I proceed from the understanding that in the final count the awareness of this will prevail and bygones will be bygones. Trade sanctions have been imposed on Russia by several countries over Russia's actions involving the Ukraine, leading Russia to retaliate by introducing restrictions on imports on a wide range of goods, including from Australia.
