PRESIDENT TRUMP'S : TRADE + FOREIGN

President Trump sees mixing trade, foreign policy as good politics. And so he has made trade policy the connective tissue that ties together ''America First'' foreign policy and syncs up them with his political strategy for the 2020 presidential election.

He pulled the plug on  an upcoming trip to North Korea by his secretary of state, and pointed a finger of  blame at China and the global super power's trade practices

In his recent trade talks with Mexico he praised the country's president for his handling of security and agriculture.

Both developments are fresh evidence of how he has linked trade and foreign policy in his political strategy.
