Trump NAFTA talks 'at appropriate time'

President Donald Trump has told reporters he will renegotiate the North American Free Trade Agreement "at the appropriate time".

Trump's remarks came at the start of a meeting at the White House with about a dozen union leaders, where he pledged to stop trade deals that harmed American workers.

He noted that earlier in the day he signed a memorandum announcing the US's intention to withdraw from the multi-nation trade agreement known as the Trans-Pacific Partnership.

Trump said he wanted future trade deals to be between just two countries.
