Mexican President Vicente Fox said both Venezuela and its President Hugo Chávez were two issues he and his US counterpart George W. Bush addressed during a meeting on Thursday in Mexican resort Cancun.

"We talked about Venezuela. And voiced concern on whether it is interfering and meddling in other countries. We talked about the need to guarantee democracy in these countries," Fox told TV network Televisa, DPA reported.

Fox is taking part in Cancun in a tripartite summit including the United States, Mexico and Canada. The Mexican ruler referred to claims in Mexico that Chávez is meddling with the Mexican electoral process to favor opposition leftist candidate Andrés López Obrador ahead of the presidential election next July 2nd.

The candidates for ruling party Partido Acción Nacional, Felipe Calderón, and for Partido Revolucionario Institucional (PRI,) Roberto Madrazo, argue Chávez is interfering with Mexican affairs.

On Thursday, Fox told reporters that Mexico would not resume ambassador-level relations with Venezuela as long as Chávez does not apologize, DPA reported. The Mexican Government claims the Venezuelan ruler should apologize for calling Fox "a puppy of the empire."
