President Trump demanded lower oil prices and a worldwide drop in interest rates as he remotely addressed the World Economic Forum in Davos Thursday. Trump also slammed European trade policies and regulations as he vowed to impose tariffs on companies that produce goods outside the U.S.

President Donald Trump: “Come make your product in America, and we will give you among the lowest taxes of any nation on Earth. We’re bringing them down very substantially, even from the original Trump tax cuts. But if you don’t make your product in America, which is your prerogative, then, very simply, you will have to pay a tariff.”

On Wednesday, Trump made his first call to a foreign leader since returning to office, speaking with Saudi Arabia’s Crown Prince Mohammed bin Salman. Saudi media reported after the call that bin Salman vowed to invest $600 billion in the U.S. over the next four years. Trump suggested he could make his first overseas trip as president to Saudi Arabia, as he did in his first term. Trump is expected to push hard for a normalization agreement between Saudi Arabia and Israel. Saudi Arabia has said Palestinian statehood is a condition of normalization with Israel.
