According to the latest quarantine relaxation announcement, vaccinated non-residents from the US and most other countries will soon be able to enter Hong Kong, perhaps by some time in July.
They'll of course be subject to all the same testing and quarantine requirements that apply to vaccinated HK residents.
Nonetheless, it's quite a surprising development. I didn't think HK would be re-opening to non-residents until next year.
