President Trump arrives in Poland on Wednesday afternoon. Over the next few days, he'll be attending a Group of 20 summit and meeting with a wide array of world leaders.
It's likely none of those meetings will be more closely scrutinized than Trump's first face-to-face sit-down with Russian President Vladimir Putin.
Trump has often said he would like to see closer ties between the U.S. and Russia. But that has been complicated by Russia's meddling in the 2016 presidential election.
