Generally you should always have multiple hardware U2F tokens in case you lose one. All sites that support hardware U2F should support registering multiple tokens for this reason. However some sites you can use TOTP as a backup for hardware U2F tokens and vice versa, so two tokens is not really necessary. But it depends.
Yubikeys are probably made in China but I don’t know any fully Chinese companies that sell them. The solo keys company is interesting because it’s all open source hardware & software.
No, the main thing separating hardware U2F tokens from crypto hardware wallets is that with hardware U2F tokens the key is totally baked into the token and can’t be exported, so it will be lost forever if the token is destroyed. Crypto hardware wallets are unique in that they let you export & import the key. Sorry I edited the post that you’re replying to a few times with extra details so you may not have read them.
Thanks!
Why two hardware keys? Do sites let you register more than one at the same time?
Are there any Chinese hardware key manufacturers?
I like the idea of archaeologists discovering my blockplate in 3,000 years like a modern-day Sumerian tablet.

Oh—you mean you can make one key into a clone of another?
