Trump is probably taking bad advice again. Either that or he has lost all confidence in his abilities to deal with China on trade and would rather go with Obama's ideas. I say that because:

Despite Trump's fiery rhetoric and crackdowns, Kudlow also suggested late last week that the president was attempting to find a "coalition of the willing" to take China on over trade. Some lawmakers and experts speculated that the "coalition" could be the TPP nations.
Just like everyone else here, I'm guessing. However, whatever the case, this would be another lie to add to his campaign promises!
