A simple extension of the Standard Model (SM), based on the gauge group SU(3)C x SU(3)L x U(1)Y with Y being the hypercharge, is considered. We show that, by imposing an approximate global SU(2)L x SU(2)R custodial symmetry at the SM energy scale, the Z - Z' mixing is absent at tree level. Tree-level flavor-changing neutral currents (FCNCs) are also reduced to three particles, namely Z', a CP-odd Higgs and a CP-even Higgs.
