In a free-wheeling speech to world leaders at the World Economic Forum in Davos, Switzerland, President Trump made a series of contested claims.
Trump touched on his desire to obtain Greenland from Denmark - which he referred to as a "small ask", America's contribution to Nato, and wind energy in China.
His address - which lasted for more than an hour - contained a number of false assertions which BBC Verify has been looking at.
For weeks, Trump has spoken about his desire to acquire Greenland, a largely self-governing territory of Denmark. He has said it is critical to US national security.
At Davos, he said that after World War Two "we gave Greenland back to Denmark," adding: "How stupid were we to do that?"
