Meydan Freezone Autorithy does not seem to think so:

Also, you haven't answered me about what will happen to offshore companies! Why can't they tax freezone on foreign income and leave it exempt for offshore
Otherwise you could just open a company, get a residence visa and work with an offshore UAE company like a Rak ICC
Don't go very far today Portugal allows you to do what you say by staying in Europe and opening a company in Delaware or Hong Kong or even an LLP in the UK
According to what you say it would be enough to open:
Company in Dubai anywhere just to get residency visa leaving it inactive
Then open an offshore RAK ICC as a holding company
Open a company in Hong Kong, Delaware or UK held by RAK ICC and administered by a trustee
0% tax company collects > RAK ICC company receives dividends > RAK ICC distributes Dividends to personal Emirati account
All without paying a euro in tax
End of story and taxation
