President Donald Trump will meet next week with Russia's Vladimir Putin during a trip abroad that will take him to Poland and Germany.

The White House would not commit to a discussion about election hacking during the pull aside at the G20 summit in Hamburg that HR McMaster, the president's national security adviser, and Gary Cohn, his national economic adviser, previewed to the press on Thursday afternoon.

'It's really going to be whatever the president wants to talk about,' McMaster said.

Cohn told reporters, 'We don't have an agenda set up for these meetings right now.'

President Donald Trump will meet next week with Russia's Vladimir Putin during a trip abroad that will take him to Poland and Germany

At the summit the White House says that Trump will also meet with Britain's Theresa May

He'll meet with Mexico's Pena Nieto for the first time on the sidelines of the summit, as well

McMaster said a goal of Trump's meetings at the G20 would be for the US and the West to agree on 'a common approach to Russia' and for them to 'develop a more constructive relationship with Russia, but he's also made clear that we will do what is necessary to confront Russia's destabilizing behavior.'

At the summit the White House says that Trump will also meet with Germany's Angela Merkel, Britain's Theresa May, Japan's Shinzo Abe, South Korea's Moon Jae-in, China's Xi Jinping, Mexico's Enrique Pena Nieto, Indonesia's Joko Widodo, and Singapore's Tony Tan.

Trump has met most of the leaders on other occasions. His face-to-face with Pena Nieto will be a first, though. They called off a White House summit earlier this year at the height of a dispute over Trump's Mexican border wall.

The talks will be quick, Trump's advisers explained, and the president will speak to world leaders about whatever topics he sees fit.

As it pertains to Russia, Trump will focus on confronting the country's 'destabilizing behavior' McMaster said 'and come up with a strategy to do that.'

'Nobody wants a major power at war,' he said, 'What is it that we have to be able to put in place to be able to deter conflict.'

Trump spokeswoman Sarah Huckabee Sanders appeared on camera at a televised briefing immediately after and would not promise, when pressed, that Trump would bring up the election hacking when he meets with the head of the Kremlin.

'Obviously I'm not gonna get ahead of the president's conversation,' she said.

Officials had testified last week that 21 states had their voting systems tampered with and some even had their data stolen. No votes tallies were effect, they said, yet warned that Russia was likely to attack America's election infrastructure again.

A report then revealed that the Obama administration knew about Russian interference sooner than it said.

Trump hit his predecessor, Barack Obama, in tweets this week for doing 'nothing' about the hacking when he found out about it and demanded an apology for charges of collusion.

White House Press Secretary Sean Spicer said Monday that Trump's cybersecurity executive order and an election commission he created would help prevent hacking from happening again.

He said he did not know what additional steps the president thinks that Obama should have taken before the last election to prevent Russian meddling and could not say, in any detail, what Trump would do that's different.

'I do know, when it comes to how the President works, he doesn't telegraph what he's going to do on a lot of these things. He does a lot of quiet diplomacy, he enacts things, and so until we're ready to announce something, we're not going to telegraph it through here,' he said of sanctions legislation that will son be on the president's desk.

Obama said he issued a stern warning to Putin on the sidelines of a similar summit last fall, contrary to Trump's Twitter claims.

In terms of his ask on climate change, an official said, 'He's going to ask for a fair and level playing field'

Officials left the door open Thursday to an additional lecture from Trump.

As news of the meeting circulated, the US senate voted to put sanctions on Russia on its second try, after an earlier bill was sent back by the House out for a rewrite. It is expected to pass in the lower chamber this time around and should end up on the president's desk before he sees Putin.

Treasury Secretary Steve Mnuchin would not say what the president plans to do with it, yet suggested that it was from his standpoint unnecessary.

'You've seen we've used sanctions in other areas. We will continue to use these. So notwithstanding anything Congress passes, I can assure you this administration and the Treasury Department will use sanctions to the maximum amount available by law,' he said.

Mnuchin added, 'We don't need Congress to tell us to put on more. We're going to do more whether they tell us or not.

'Russia sanctions, we've got plenty of those on as well.'

McMaster had echoed Secretary of State Rex Tillerson's interest in working with the Russians on areas of mutual interest, like the crisis in Syria, in the first White House briefing, one that was not televised.

Other topics on Trump's mind will be terrorism, trade, trade, energy and the environment, he said.

In terms of the president's ask on climate change, and his expected talk with Merkel, Cohn said, 'He's going to ask for a fair and level playing field.'

'We cannot be in a position where the United States is cutting and cutting emissions while other countries continue to grow until 2030, that doesn't seem like a fair and level playing field. '

Trump's meeting with Merkel will be his first since he announced dramatically announced his decision to pull the US out of an international climate change agreement that the German leader has aggressively supported.

Merkel had said in a speech to German parliament Thursday, 'We can not and will not wait for the latest in the world to be convinced by the scientific evidence for climate change.

'The Paris agreement is irreversible and non-negotiable and I am determined to carry out the negotiations at the G20 Summit so that they can serve the Paris climate agreement.'

Trump indicated in Thursday afternoon remarks of his own that he's not going to budge.

The US president said at a Department of Energy even that 'in order to protect American jobs, companies and workers' he was exiting 'the one-sided Paris climate accord.'

'And I won't get into it, but believe me, that really put this country at a disadvantage. No. 1, we weren't playing on the same field,' he said. 'The money that we had to pay was enormous. It was not even close.

Trump said, 'Maybe we'll be back into it someday, but it will be on better terms. It will be on fair terms. Not on terms where we're the people that don't know what we're doing.

'So we'll see what happens, but I will tell you we're very proud of it.'

Before Trump arrives at the G20, he will spend a day in Warsaw, Poland attending the Three Seas Conference, where he will speak to 12 central European, Baltic and Western Balkan leaders about infrastructure development and energy security.

He will also speak to the Polish people from Krasinski Square, McMaster said, laying out a vision for America's transatlantic alliance with the NATO ally.

A meeting with Polish President Andrzej Duda is also on the books, the White House stated.
