The United States will include a clause preventing currency manipulation in all future bilateral trade deals, President Donald Trump said Thursday, as he criticized the Trans-Pacific Partnership economic pact for not prohibiting the practice.

"We're going to have very, very strong controls over monetary manipulation and devaluation, which they didn't have in TPP," Trump said in a speech in Philadelphia, taking aim at the practice of deliberately weakening currencies to boost export revenue.

The president also said the United States would withdraw from bilateral trade deals deemed as not treating the country fairly, having on Monday ditched the 12-party Asia-Pacific pact.
