President Donald Trump incorrectly placed the blame for high prescription drug prices in the U.S. on foreign nations, making the comments Monday when signing an executive order intended to lower their cost.

U.S. President Donald Trump's executive order on drug pricing threatens Roche's planned $50 billion investment in the United States, the company said on Wednesday. Trump's order, signed on Monday, directs drugmakers to lower prices of brand-name medicines to align with those in other wealthy nations.

The executive order directs Trump's administration to take actions against "discriminatory" policies in foreign countries that suppress drug prices.
