Donald Trump's America First face to face with Xi Jinping's China Dream as the two leaders meet for the first time.
From stealing jobs to putting up trade barriers to manipulating currency -- Trump has accused China of being responsible for much of America's economic woes.
Can the business magnate drive a hard bargain with President Xi Jinping? Will the US President live up to his promise of a turnaround in relations?
Besides economics, there are other thorny issues.
China's reluctance to rein-in North Korea and expansionist designs in the South China Sea region worry Washington, while Beijing is wary of President Trump's views on the one-China policy.
There are sharp divisions and Trump has already tweeted that it will be a difficult meeting.
