Your points boil down to: a) China keeps on exporting, b) liars are caught and Trump didn't caught the Chinese regime lying, c) The Chinese regime enforced quarantined effectively. From these points, only the third has any relation with and impact in the outbreak of covid19 within China. However, as the virus is reported to have an asymptomatic incubation period that can be as long as 2 to 3 weeks, and as there are reports from within China that show that covid19 can be transmitted at over 4 meters, then, as we have seen in Italy and Spain, the impact of this measure would only start to show with that much of a lag. I admit I am not an epidemiologist, but claiming that an epidemic was just stopped on it's tracks almost instantly has little to no credibility. For that to be even remotely realistic, there needed to be zero asymptomatic carriers from one day to another. To add insult to injury, the Chinese government reported that the only new covid19 cases experienced within China came from foreigners who imported the disease. I'm sure the measures imposed by the Chinese regime has a profound impact on the epidemic, but none of the official reports appear to have any credibility whatsoever. A disease with a 1 to 3 week incubation period does not stop spreading or killing people from one day to the other. What does stop immediately is how you chose to report the data, specially counting the dead.
