Trump landed Thursday evening. He injected fresh drama into the meeting on his trip south when he canceled a planned meeting with Russian President Vladimir Putin over Russia's seizure of Ukrainian vessels.
The president canceled on Putin not long after his former lawyer, Michael Cohen, revealed he had lied to Congress to cover up that he was negotiating a real estate deal in Moscow on Trump's behalf during the Republican presidential primary in 2016.
Trump faces a series of diplomatic challenges at the G-20, most notably whether he can strike an agreement with Chinese President Xi Jinping to ease trade tensions that have rattled financial markets.

Trump tweeted his decision Thursday after departing Washington for a world leader summit in Argentina, where he and Putin were to meet.
Trump says "based on the fact that the ships and sailors have not been returned to Ukraine from Russia, I have decided it would be best for all parties concerned to cancel my previously scheduled meeting in Argentina with President Vladimir Putin. I look forward to a meaningful Summit again as soon as this situation is resolved!"
Russia recently seized three Ukrainian vessels and crews. Russia said Ukraine didn't have permission to pass between Russia's mainland and the Crimean Peninsula. Ukraine insisted its vessels abided by maritime laws.
