"When Brazil sneezes, Argentina catches pneumonia."
The saying is used by Argentines to describe what can happen if their neighbor is struck by economic malaise.
Argentina is Brazil's main trading partner in Latin America and would be hardest hit should Brazil – currently in the midst of a political crisis and eking out meager growth – slip back into recession.
