Brazil and Argentina wish to forge closer ties, including by developing a common currency, a joint statement released by the nations’ presidents said. The Community of Latin American and Caribbean States summit comes as calls for regional integration grow among leaders in South America. The stage is set for a discussion on a single currency for South America’s two largest economies at a summit in Buenos Aires on Tuesday. Both nations say a single currency could reduce “external vulnerabilities.” Do you think that every continent need to have their own common currency ?
