The interview’s key exchange:

WSJ’s Bob Davis: “[T]he Chinese No. 1 goal in this G-20 is to get you to delay or suspend that [increase in the tariff rate on some Chinese imports from 10 percent to] 25 percent on January 1. … [A]re you willing to do that?”

Trump, who’ll meet Chinese President Xi Jinping at the summit: “I think it would be highly unlikely.”

This suggests that, as Trump has been telling people he talks to regularly, he doesn’t expect a breakthrough.

A breakthrough would mean any kind of deal — even a temporary one — to stop Trump from ratcheting up China tariffs in January, as he’s scheduled to do.
