Many people here are conflating "stop" with "make it non-exponential". "Stop" just ain't going to happen, and hasn't happened anywhere (Vietnam reports they have, but come on). China reports bending the curve away from exponential. That is the goal. It is a very important one.

It's not just no longer exponential. The number of active cases is China is in decline. How long they can keep that going is debatable. But as of right now they are effectively stopping it.

That is not stopping. Extrapolating your trend to infinity suggests stopping is plausible. Latest data I see is 134 new cases per day in China. Let's take those numbers at face value and believe them (no sarcasm intended). However, these are just known cases. China is not testing everyone. As managing the spread becomes more successful it becomes cost and manpower prohibitive to test enough people to catch them before they spread significantly.

China has moved the R0 below 1 through some combination of behavior changes, else the number of active cases wouldn't be going down.

If they can keep it below 1, it will die out. It's possible there are many more unknown cases, but if unknown cases are increasing, confirmed cases should be too.
