I have a Cuban passport & Chinese Business Visa -Can I enter HK ?

Hello,
I hold a Cuban passport, but am a Canadian permanent resident, I have been living in Canada for many years.

I have a Chinese business M type and will be travelling to China for a week.
I understand that with a Chinese business M type, you are allowed to enter Hong Kong as a visitor for 7 days.
Can anyone confirm if, as a Cuban passport holder, this also applies to me?
I am asking because Cuba is one of few countries where one cannot work in HK, though I will just be there to visit.

Thanks!
