Moving charges and magnetic fields: does one effect cause the other?

I am a little bit confused about a basic point in electromagnetism, hope someone might help. I know that (1) a moving charge creates a magnetic field around it. I also know that (2) a magnetic field (also that generated by a permanent magnet) affects a moving charge, in the way captured by the formula for the Lorentz force (the magnetic part of it). My question is: how exactly are the two facts related? Does a magnetic field affect a moving charge BECAUSE OF the magnetic field created by the moving charge (that is, (2) BECAUSE OF (1). Or rather are the two facts (1) and (2) to be thought as causally independent? That is, a magnetic field affects a moving charge, but NOT BECAUSE of the magnetic field created by the moving charge.
