>> As leaders from the world's top economies met in Hamburg for the G-20 Summit, this was the most anticipated moment. A handshake between Donald Trump and Vladimir Putin as they meet in person for the first time. Ahead of an official sit-down between the two later on Friday. Every word, facial expression and gesture will be analyzed as the two presidents size each other up.
Trump says he wants to find ways to work with Russia, and has praised Putin in the past. But just days before the summit, a sudden change of tune during a speech in Poland.>> We urge Russia to cease its destabilizing activities in Ukraine and elsewhere. And to instead join the community of responsible nations in our fight against common enemies.
>> Trump making his clearest commitment yet to NATO's oath of mutual defense to counter any threat from Russia. These words making Friday's chat perhaps more awkward than expected, and Syria, Iran and Ukraine won't be the only topics requiring careful navigation. An ongoing investigation into whether Moscow meddled in the US presidential elections may also be a sore spot.
Another big one will be climate change. Trump and Putin are meeting 15 minutes after climate talks are set to begin. Two world leaders skipping that debate isn't likely to go down well with host, Germany. Chancellor Angela Merkel wants climate to be top of the agenda this weekend with a focus on the Paris Accord, which Trump has vowed to leave.
White House officials declined to offer details on what Trump and Putin will talk about, but some fear that, as a political novice, Trump will be walking in under prepared.
