“When China’s top leader, Xi Jinping, and President Trump meet in Washington this week, the two men will be operating on vastly different clocks,” the New York Times reports.“The American president is constrained by the immediate demands of a midterm election in November and a grinding war. The Chinese leader is gearing up for a norm-shattering fourth term as head of the ruling Communist Party, that will keep him in power for another five years.”“For Mr. Xi, the disparity in political realities gives him an edge in maintaining the truce that the two countries reached last year. A renewed trade fight would hit American consumers right before the election — a risk Mr. Trump can ill afford. China’s economy is struggling too, but Mr. Xi answers to no electorate, giving him the patience to prolong the détente on his terms.”
