Peru is considering moves to face "unacceptable meddling" of Venezuelan President Hugo Chávez in the Peruvian electoral process, Wednesday said Foreign Affairs minister Oscar Maúrtua in Lima.

"In diplomacy, you have to make decisions serenely," said Maúrtua when asked why his country does not take stronger measures in the face of Chávez' behavior such as filing an official complaint before the Venezuelan government or the Organization of American States.

Bilateral relations deteriorated last week when Chávez publicly praised nationalist presidential candidate Ollanta Humala. Tensions escalated on Tuesday, when Chávez called Social Christian presidential candidate Lourdes Flores "a candidate of oligarchy," DPA reported.

"This is a reiterated behavior we cannot accept," said Maúrtua.

He reminded that OAS and UN provisions prevent member states from interfering in other countries' internal affairs. He did not rule out the possibility to take the issue to such international bodies.

Meanwhile, Flores, Humala's major opponent in next April 9th presidential election according to polls, rejected Chávez' comments. "This is an unacceptable meddling. We are not going to tolerate that a foreign ruler comes to tell us Peruvians how to vote. The future of Peru is in the hands of Peruvians."
