The spokesman for Russian leader Vladimir Putin is shrugging off President Donald Trump's call to reduce Russia's dominance of the natural gas supply for Eastern Europe.

Putin spokesman Dmitry Peskov tells reporters, "There's no energy monopoly in Europe" ahead of the planned meeting of the Russian and U.S. leaders in Hamburg, Germany.

Trump said in a speech in Poland Thursday that he wants to make sure Poland and its neighbors are "never again held hostage" to a single supplier of energy.

Peskov says: "All this will be decided by the market, it should not be decided politically."

The Kremlin says that President Vladimir Putin and U.S. President Donald Trump have exchanged a handshake and a few words ahead of their sit-down at the G-20 summit.

Putin's spokesman Dmitry Peskov told reporters that Putin and Trump "shook hands and told each other that they will shortly have a separate meeting."

Asked about Trump's tweet that he's looking forward to meeting with Putin and they have "much to discuss," Peskov answered that the Russian president is also looking forward to the encounter.

The long-anticipated Putin-Trump meeting will be closely watched to see whether Trump brings up Russia's meddling in the 2016 U.S. presidential election. The two presidents are expected to focus on the Syrian war, the Ukrainian crisis and the fight against terrorism.

President Donald Trump is tweeting that "everyone" in Hamburg, Germany is talking about the Democrats' response to Russian election hacking ahead of his highly-anticipated meeting with Russian President Vladimir Putin.

Trump writes ahead of his arrival at the group of 20 summit: "Everyone here is talking about why John Podesta refused to give the DNC server to the FBI and the CIA. Disgraceful!"

Podesta was the former chair of Trump 2016 rival Hillary Clinton's presidential campaign. Podesta did not run the Democratic National Committee.

U.S. intelligent agencies have blamed the hacking of the DNC as well as Podesta's personal email account on the Russian government.

After weeks of anticipation, President Donald Trump and Russian President Vladimir Putin are preparing to meet at an international summit in Germany.

Friday's much-anticipated encounter comes at a pivotal time in U.S.-Russian relations. Trump will be closely watched to see if he confronts Putin over Russia's meddling in the 2016 presidential election.

U.S. lawmakers and federal investigators are continuing to look into Russia's election interference, along with possible collusion between Trump campaign associates and Russian government officials.

That puts Trump under intense scrutiny over how he handles the sit-down with Putin, a former Russian intelligence agent known to come well-prepared to meetings like this.
