It is shown that non-returning parallel communicating grammar systems with -free contextfree components can generate any recursively enumerable language. Since it was proven that such systems can be simulated by returning PC grammar systems with context-free components, the result extends to those.

We prove that all recursively enumerable languages can be generated by context-free returning parallel communicating grammar systems by showing how the parallel communicating grammars can simulate two-counter machines, a class of Turing machine variants which is known to be computationally complete.
