(Bloomberg) --
U.S. President Donald Trump jetted out of Davos, but not before igniting another round of international trade tensions.
Less than a week since inking an interim trade deal with China, Trump and his team took aim at European Union nations and the World Trade Organization.

My colleagues Josh Wingrove, Jenny Leonard and William Horobin deliver the full story of Trump's Davosian trade tirade.
Temperatures predicted to be between -6°C and 8°C; depth of snow: 51 centimeters.

As the gulf between the rich and everyone else continues to grow, more than 100 billionaires are in Davos this week to rub shoulders with bankers, politicians and other grandees. The elite group, worth about $500 billion, includes regulars like Bridgewater founder Ray Dalio, Blackstone Chairman Steve Schwarzman and JPMorgan CEO Jamie Dimon.
“I was worried about him, because he's one of our great geniuses, and we have to protect our genius,” Trump said about Tesla CEO Elon Musk. “You know, we have to protect Thomas Edison and we have to protect all of these people that came up with originally the light bulb and the wheel and all of these things.”
For the second year in a row, a Cannabis House has opened up in Davos, promising to be “a little more formal and more professional” than last year's, according to Jason Paltrowitz of OTC Markets Group, one of its sponsors. Meantime, inside the conference center, delegates got to hear the story of a company developing a hallucinogenic drug to treat addiction to opioids.
