President Trump signed three executive memos on trade Monday morning-one withdraws the U.S. from the Trans Pacific Partnership (TPP), another reinstates the Mexico City Policy dealing with non-governmental organizations (NGOs) and abortion access, and a third freezes federal workforce hiring.

TPP was an enormous trade deal that would have aligned the U.S. and 11 nations in the Asia-Pacific region including Japan, Australia, Vietnam, Canada and Mexico under an agreement that would have eliminated thousands of tariffs and streamlined regulations. The countries involved in the deal collectively conduct 40 percent of global trade.

The TPP was negotiated under former President Barack Obama, but never ratified by Congress, so withdrawing from it will not have an immediate, real effect on US economic policies, although it does signal a new and very different US outlook on trade under Trump.
