We analyze an open many-body system that is strongly coupled at itsboundaries to interacting quantum baths. We show that the two-body interactionsinside the baths induce emergent phenomena in the spin transport. The systemand baths are modeled as independent spin chains resulting in a globalnon-homogeneous XXZ model. The evolution of the system-bath state is simulatedusing matrix-product-states methods. We present two phase transitions inducedby bath interactions. For weak bath interactions we observe ballistic andinsulating phases. However, for strong bath interactions a diffusive phaseemerges with a distinct power-law decay of the time-dependent spin current$Q\propto t^{-\alpha}$. Furthermore, we investigate long-lasting currentoscillations arising from the non-Markovian dynamics in the homogeneous case,and find a sharp change in their frequency scaling coinciding with the triplepoint of the phase diagram.
