Argentinian elected president, Cristina Fernandez de Kirchner, is already showing she's not dumb. Cristina is indicating she will focus on Argentina's commercial relations with Brazil, more than with venezuela:

"Relations with Brazil are very good and the fact Brazil has been chosen as the first country to visit is symbolic", said Foreign Affairs minister Jorge Taiana who has been confirmed in that post in the incoming cabinet December 10.

(...) "Brazil is and will be Argentina's priority relation to show the world, maybe even more than during the current administration of President Nestor Kirchner. We must not forget that during the first two years of President Kirchner they weren't (Kirchner and Lula da Silva) always on the same wave band", said an undisclosed member of Taiana's team.

"The reading must be first Brazil and maybe later (Hugo Chavez) Caracas", added the source. Cristina Kirchner will be traveling with Jorge Taiana who underlined that "we're going to review (with Lula da Silva) all issues". (Source)

I guess this new approach has nothing to do with the oil recently discovered in Brazil, hu? After all, Lula is much nicer than Hugo Chávez; who wouldn't prefer to deal with him? :P
