Donald Trump came away from his meeting with Chinese leader Xi Jinping full of bombastic optimism.

He called it a great success and rated it 12 on a scale of 1 to 10. China was less enthusiastic. Beijing's initial statement sounds like an instruction manual, with Xi urging teams on both sides to follow up as soon as possible.
