Doesn't look like the trend there is really changing since it peaked around March 8th. Seems pretty consistently in the low hundreds of new confirmed a day.

If you scroll down the page there's a graph that helps to visualize it: https://www.worldometers.info/coronavirus/country/south-kore...

Look at the infection rates in those countries: they're S-curves. New infections are being found, but the rate of increase is far lower than it was previously, and the majority of cases are cleared up. That shows they're likely on the tail end of the problem.

For European countries and the US, the curve looks asymptotic. There's no telling how high it'll go at this point.

For China many Chinese emigrants are returning home with the virus with them. as they don't trust their local healthcare systems.

Almost half of them are actually an influx from other countries, mostly overseas Korean in EU and US.
