I double-checked the source for each listed event.
* The first event on National Review's list (12/6) is not confirmed by the linked Lancet article. There is nothing resembling what NR quoted, supposedly from Lancet. While some Prog orgs claim NR lied, my guess is that either Lancet edited their article or the incorrect link is in NR's article. Other sources have information consistent with or ante-dating NR's 12/6 date.
* The South China Morning Post is over a century old, and is based in Hong Kong. The Straits Times is ~175 years old and is based in Singapore. Their information is vaguely sourced, to some degree, that's the nature of getting information from inside China.
* Some of NR's source articles are behind paywalls. While I found alternative sources for some, others I simply omitted. I won't support paywalls by paying or linking blocked information.
* Some source articles are Chinese language. I used Google Translate to verify the content.
* The Congressional Research Service article is long. The timeline is some 29 pages long and incredibly detailed. It provides footnotes for every entry, but some of the urls have typos. As best I know, all of the urls in my timeline below are valid.
