Brazil and Argentina are expected to announce preliminary plans about a common currency this week. The two countries are now politically aligned, following the recent election of Brazil’s former president, Luiz Inácio Lula da Silva of Brazil.

Brazil may also be concerned about Argentina deepening economic ties with other countries, said Susan Pozo, an economics professor at Western Michigan University.

“They may want to forge ahead in terms of linking themselves more closely to Argentina,” she said.
