In 2017, weeks after Donald Trump’s first presidential election victory, Xi Jinping became the first Chinese head of state to address the World Economic Forum in Davos, Switzerland — winning applause as he inveighed against protectionism and declared that a trade war would hurt both sides.

Among Trump's first acts in office on Monday was to order U.S.'s exit from the World Health Organization and Paris Agreement.
