President-elect Donald Trump says the US will quit the Trans-Pacific Partnership trade deal on his first day in the White House.
He made the announcement in a video message outlining what he intends to do first when he takes office in January.
The TPP trade deal was signed by 12 countries which together cover 40% of the world's economy.
Mr Trump also pledged to reduce "job-killing restrictions" on coal production and stop visa abuses.
But there was no mention of repealing Obamacare or building a wall on the southern border with Mexico, two actions he said during the campaign he would do as soon as he assumed power.
His surprise election win two weeks ago has sparked protests across the US.
