Regulating an economy through monetary policy (interest rates - the usual
method) is far more problematic than most folks would ever imagine. It's
been likened to pulling a brick with an elastic band - and that's not a
bad analogy. It's incredibly difficult to get the rate set right in order
to produce long-term stability and the optimally desired 'goldilocks
economy'. That's why there's normally a panel of economic advisers
involved. It's too complex a decision for just one man.

 Regulating an economy with pouring government money into crucial
sectors and infrastructure, seems vastly more effective.
China does this, and remember Trump-level corruption can get you
a death penalty.

China has been playing catch-up until recently, as Japan did earlier.
When you've got foreign examples of what does work, it a lot easier to pour the investment into sectors that you know can use it, because other advanced industrial countries did it first and demonstrated that it could work.
Once you've caught up, you got to make your own developments decisions, and that's a lot more difficult. The rule of thumb I heard was that about 30% of development projects developed something useful and profitable, and the remaining 70% didn't earn anything out of the effort put in,and many got cancelled before they'd got anywhere at all.
