On one side you've got the doom and gloomers who in some cases hate Trump so much they're cheering for a deep recession, and on the other side you've got people like Yellin who think the economy has enough momentum to avoid a recession.
China is playing hardball because they think the U.S. is behind all the upheaval in HK (they're correct) and they've got to project strength in spite of the fact that there's alarm bells all over their economy, from bank failures to plummeting factory orders.
To think it could be reversed by coming back to the table, reducing or eliminating tariffs, stop state sponsorship of intellectual property theft etc. etc. But that's not what China is, it's a corrupt authoritarian regime that built its economy on near slave labor, currency manipulation and corporate theft. Sadly aided and abetted by a laundry list of American companies. China is also a massive polluter who is escalating its emissions, building hundreds of new coal fired power plants and turning a blind eye to the reintroduction of chlorofluorocarbons into the production process in some provinces so as to increase efficiencies.
