What did Trump and Xi Jinping talk about?

Can there have been any less news coverage of the top meet-up yet between Donald Trump and a foreign leader than there was for the 24 hours Xi and Trump spent at Mar a Lago. Crickets and a hopeful sign.. El Sisi, Abdullah II, Netanyahu, Merkel, May had bigger photo ops,and made joint public statements.  It was crickets, however, for the meeting with the leader of the second-strongest power on earth, leader of the world's most populous nation, leader of America's largest source of imports and leader of the country most able to position itself as a warring enemy or a respected competitor.
On top of that Thursday night, after the steak and before the sorbet,  president Trump told premier Xi that he's bombing a Syrian airfield.  I jumped out of bed Friday morning to hear the joint communique.

No communique.  Instead, intriguing bits of goodwill.  "Lots of very bad problems will be going away" was the extent of American verbosity plus a cute moment of the grand-kids singing in Chinese to the guests.      This reads to me as a peace indicator, not a warlike one.   Keeping things private and personal is the right setting to explore new ground. Everything public would be posturing, locking un-examined positions in place.

And what's with "Yi-Wan-Ka" and the Trump grandchildren singing in Chinese?  Another indicator for co-regency instead of war.   Ivanka is a life model to many Chinese women.

Two days later, a little information emerged.
