There is currently a diplomatic row between Mexico and Venezuela. At the crux of things is whether Latin America should formulate a free trade zone that would enrich the whole western hemisphere.

This arrangement can only help the poor of the region. Daniel has an excellent round up of the current spat between Chavez and Fox. It is also interesting to note that both Mexico and Venezuela are the larger oil exporting nations of the Americas.
