Mohammed Al-Jadaan says there will be "plenty of opportunities for sponsors" despite Premier League clubs voting on Monday to impose a temporary freeze on deals with businesses linked to their owners.
Al-Jadaan believes it is "good for the whole football community" that there is another "serious competitor" to the English crown. The Saudi Arabia Investment Fund's (PIF) £300m takeover of the Magpies has been met with widespread concern from human rights groups and the other Premier League clubs.
This is PIF investment and basically, they are investing in the club but also the community, the academy and the stadium itself.
With sponsorship particularly, we do that not only with clubs that we own but with different clubs and events.
I don't know the technicalities of the association in the UK. But I would say if people were worried about competition amongst clubs, and particularly now we have invested in one of them.
I think there will be plenty of opportunities for sponsors and plenty of opportunities for the club.
Newcastle threatened to sue the Premier League and the 18 clubs that voted in the temporary sponsorship freeze because they believe it is unlawful. Manchester City abstained from the vote.
The temporary freeze will be in place for a month while talks are held about a permanent rule change.
One Premier League executive said: "If we didn't have the ban, there would have been nothing to stop Newcastle signing a say £100m naming rights deal for their stadium with a Saudi company linked to their owners.
They could then have used that money to buy players in January and get around our financial fair play rules.
