"The victory of Humala, contrary to what his opponents say, does not jeopardize the economic development," said the Peruvian novelist.

"I think he has given enough proof, especially in the second round, that he will respect political democracy, market economy, private property and is not going to jeopardize Peru's notable economic growth, but will spread the fruits of this development throughout the country," he added.

Vargas Llosa also advised Humala to put an end to the climate of hostility that encourages polarization in the country.

"I think (Humala) must multiply his gestures to reconcile these bitter adversities, showing that he was elected president of Peru and not president of his supporters. He will govern for all Peruvians. All Peruvians of good will are called to assist in this daunting task which is to fight poverty, underdevelopment and strengthen our democratic system that is very weak," he said.

Vargas Llosa said he will be keeping a close eye on the government. "If this candidate doesn't fulfill his promises, I will certainly intervene with the same energy and conviction that I intervened in this campaign to support Ollanta Humala," he said in a telephone interview with Panamerica Televisión from Spain.

He concluded by saying that democracy is based on the "new middle class and young people who with great strength will leave poverty behind and become the future of Peru."
