China's problems boil down to demand, derisking, demographics, and debt, economist says

• China is facing the "four D's": demand, derisking, demographics and debt, an economist said.
• The country's leaders are going about solving the problem the wrong way, focusing on the supply side instead of demand.
• Meanwhile, foreign investment is bleeding out of China and officials don't seem to grasp the seriousness of the matter.
