Please see below - There is a relationship. - I do think Fuji is competent and there is no dispute that Fuji has MF experience.
In 1998, Hasselblad began selling the XPan, a camera designed and made in Japan by Fujifilm.
In 2002, they introduced the H-System, retroactively renaming their original camera line the V-System. The H-System marked an essential transition for the company. It dropped the traditional Hasselblad square negative format, instead using 6×4.5 cm film and a new series of lenses. The then owners had no confidence in Hasselblad's already advanced digital project returning a profit, and, seeing the relative success in the market of the modern (i.e. fully automated) 645 cameras made by manufacturers like Pentax and Mamiya, closed down Hasselblad's digital department and directed all effort towards making this 645 film camera. The H-System is largely designed and manufactured by Hasselblad, with Fuji's involvement being limited to finalizing Hasselblad's lens designs and producing the glass for the lenses and viewfinders. Fuji was allowed under the agreement to sell the H1 under their name in Japan only.
XPan (1998–2006) (designed and manufactured by Fujifilm)
H-System
The camera used Fujinon manufactured lenses and prisms, thus departing from Hasselblad's long association with Carl Zeiss when it comes to lens manufacturing. Shutter in the lenses was still manufactured by Hasselblad and so is the body. Hasselblad initially invited both PhaseOne and Kodak to develop digital backs for the H-System.
In 2002 Hasselblad introduced the H series of cameras. These were purportedly designed in large measure by Hasselblad's engineers, but are built in Japan by Fuji. The lenses for the H series are all designed and made by Fuji, but specified by Hasselblad. It's interesting to note as well that in Japan the H series cameras are sold as Fuji brand cameras, with no mention whatsoever of the name Hasselblad. (This applied as well to the excellent Hasselblad X-Pan, which was simply a rebranded Fuji product)
When the H1 was first introduced that was much wailing and gnashing of teeth among the Hasselblad faithful. The move from Zeiss to Fuji lenses was the source of concern. The past few years has shown this not to have been an issue. Fuji makes some of the finest large format and scientific application lenses in the world, and Hasselblad claims to have specified the lenses for the H series cameras

The GX645AF was developed in collaboration with the world-renowned Hasselblad camera manufacturer. It is the medium format auto focus SLR camera in the world.
