“Isn't that what I said？”

No, that's not at all what you said clear as a bell, which was "the US initially did not block arrivals from China, it blocked Chinese citizens."

You were trying to justify China's criticism of the U.S. ban by painting it as discriminatory against Chinese citizens. In fact, the ban had nothing to do with Chinese citizenship. Chinese citizens who hadn't recently been in the Mainland remained eligible to enter the U.S. And non-Chinese citizens who had recently been in China were banned, unless they were U.S. citizens/residents.
