U.S. President Trump said, "The United States will no longer turn a blind eye" to some economic practices he called "predatory behaviors.", CNN reports.
"We cannot have free and open trade if some countries exploit the system at the expense of others," Trump said. "We support free trade, but it needs to be fair and it needs to be reciprocal. In the end, unfair trade undermines us all."
He aded that insisting on fair and reciprocal trade creates a system that works.
Just days before this speech at Davos, Trump slapped tariffs on imports of solar panels and washing machines.
Trump also briefly addressed the Trans-Pacific Partnership (TPP) deal that he ditched in January 2017. The remaining 11 nations revived the deal without the United States.
