[Dragonball] Is there any interplanetary culture?

There's definitely some sort of interplanetary contact happening.  Frieza and Buu both appear to be well known on many planets.  But is there any cultural exchange?  Or do people only go to other planets to murder each other?

There's a Galactic Patrol that works to protect people from interplanetary criminals, but most worlds are comparatively self-contained. While it was around, the Frieza Force was the largest organized military power in the galaxy, and there were never any notable alliances formed that were powerful enough to challenge it.
