It is shown that the Peccei-Quinn mechanism will, in the large-N limit, remove dimension-six CP-violating operators constructed solely out of gauge fields. Such operators have been recently proposed as a source of a possibly large neutron electric dipole moment. © 1991 The American Physical Society.
