U.S. President Donald Trump is set to hold his first meeting with Russia's Vladimir Putin at a G20 summit in Hamburg, Germany.

The two leaders are due to meet in the afternoon for an hour, Russian media say, though other reports suggest it could be about 30 minutes.

Here are three key things to watch out for as two world leaders initiate their first formal dialogue:

The Hand-Shake

Trump has had many awkward instances in past when it comes to shaking hands with foreign dignitaries, including the recent one with Poland's First Lady, who walked right past him to shake hands with his wife Melania instead.

The body language of both Trump and Putin will be closely observed and analyzed to get a sense of how much the two leaders were comfortable in each other's company.

U.S. Polls On The Agenda?

According to U.S. intelligence agencies, Russia interfered in the 2016 presidential election and it would be important to see whether Trump will bring up this topic with Putin later today.

"I think it was Russia and I think it could have been other people in other countries," Trump said during a joint press conference with Polish President Andrzej Duda.

Will Trump Discuss North Korea?

Russia, like China, shares a border with North Korea and has so far supported dictator Kim Jong-Un despite condemnation from the United States.

While President Donald Trump has called on his foreign allies to take action against North Korea's missile threat, it is still not entirely clear what new steps could be taken.
