China is now encouraging higher birth rates after many years of the one-child policy. But the general consensus is that it hasn’t been very successful, even with the CCP’s authoritarian power. The causes are multi-dimensional and difficult to solve: high living costs, changing social values, and younger generations who no longer want to marry young—or marry at all.

Even North Korea has to encourage women to give birth[0]; the Kim dynasty can’t simply issue an order and shoot anyone who disobeys. It simply doesn’t work that way.
