U.S. President Donald Trump threatened to take action against the World Trade Organization on Monday after media reports said he wanted to withdraw from the global trade regulator.

Trump has complained frequently that the United States is treated unfairly in global trade and has sharply criticized the WTO for letting that happen.

"WTO has treated the United States very badly and I hope they change their ways. They have been treating us very badly for many, many years and that's why we were at a big disadvantage with the WTO," Trump told reporters at the White House.
