There are structural issues in China revolving around private debt, unemployment, (lack of) employment opportunities, and both private and commercial real estate. China is overextended in a way that would make americans blush if they were paying attention. This is the nature of their economic slowdown. You could probably argue these issues are cyclical and related to an evolving economy (as you seem to be suggesting) - but I think there are deeper issues that are more cultural and far more difficult to overcome. The chinese economy isn't just evolving - it is in real distress. That pressure has been somewhat alleviated as a direct result of some of Trump's mishandling of the global economy. Trump sought to harm China and in some respects he's propped them up and given them a bit of an out. But these problems aren't just going to vanish with a few ASEAN and EU trade deals.
