Pomp and pageantry greet Trump ahead of talks with Xi

Military marching bands and flag-waving children were part of the welcome.

Trump, the eighth U.S. president to visit China, seemed to be soaking it all up, chatting amiably with Chinese President Xi Jingping, repeatedly complimenting the ceremonial display and patting him on the back -- eight back-pats and three handshakes, to be exact.

After the parade, the leaders climbed the steps of the Great Hall -- known here as "G-HOP" -- and looked out into Tiananmen Square before heading inside.
