Trump out with a tweet ahead of the summit meeting later

He's setting up a very aggressive tone ahead of the summit later. Following up from his earlier tweets this morning during the Asian session.

Considering how much he is building this up, I can imagine this going in the way that he will say he concluded "successful" talks with the other leaders on the trade front - and markets will cheer that in the near-term. But when it comes down to the nitty-gritty, nothing has really changed.
