It is fine to enter HK as a visitor for certain business activities, including: "concluding contracts or submitting tenders, examining or supervising the installation/packaging of goods or equipment, participating in exhibitions or trade fairs (except selling goods or supplying services direct to the general public, or constructing exhibition booths), settling compensation or other civil proceedings, participating in product orientation, and attending short-term seminars or other business meetings". However, visitors cannot legally take up employment or study or establish or join any business.

We routinely have non-HK clients and lawyers from our other offices out to HK to attend meetings and do associated work, but as I understand we cannot have a lawyer from another office seated in HK that is not working on a specific HK based matter.
