visa for starting a business in HK

Dear Sir, Madam,
I am a Belgian citizen planning a visit to Hong Kong on august 11th.The goal for this visit is to start a sourcing business in HK, so NOT to do business YET, but just to start up the business and open a banc account.A few days later I would like to travel to Shanghai to visit the companies that I corresponded with already.A second thing is, I am training a person from Manila/Philippines to take care of my business when I will not be in the country. Taking care of my business meaning : traveling to the companies in Shangai and HK to do quality checking of the orders I will place at those companies.  Is that person allowed to join me on this visit to learn more about those companies?So, I am not sure if I need a visa for this or not, and if yes, which kind and what is the best way to apply for it?
.Thank you in advance for a quick responce,
Kind regards,
Pascal
