Dominica has a population of less than 100,000 people and their national gross income is about $7000 USD a year. Suffice to say this is not very useful to many people.

I actually don't know if they're honoring visa-free entry (and if quarantine counts towards those days): for example, Qatari citizens have 30 day visa free entry to China, if you are unlucky and do 28 days of quarantine, do you have to leave immediately afterwards?

Anyways, yes, all of the same entry restrictions other than a visa apply: https://www.mfa.gov.cn/ce/ceqa//eng/zxxx/t1844266.htm
