China's Invisible Hand Is Distorting Global Oil Markets – Oilprice.com

The result is clear: China manages its own energy security while exporting volatility to everyone else.

The result is clear, China has the upper hand in global macroeconomics due to sheer size which provides the ability to manipulate almost any system based on Keynesian dynamics.

The biggest threat to China at this point is internal corruption. As long as they can keep this in check in their internal politics, the rest of the world is forked.

In summary --- China has broken the "free market". Macroeconomics as it has been taught for the past century or so isn't really applicable under current conditions. Undoing this would require global cooperation on a scale that is highly unlikely in my opinion.
