So, why does President Trump keep praising Xi Jinping? Because that's how you back up an opponent into a corner. If Trump says that they have a great relationship, Xi cannot come out and deny it for fear of making himself look bad. If Xi doesn't have a good relationship with the largest importer of goods (America), than his own country is gonna be on him for being an idiot. If he doesn't deny that Trump and himself have a good relationship than the DS cabal within China has no choice but to turn on Xi. After awhile of praising Xi, their DS is going to go full retard on Xi. And President Xi will have no other options than to deal with the DS in his own country. That will end up taking a heavy toll, on an already weak government idiologue.
