From the BBC:
"Brazil, India and South Africa are working to set up a free trade area they hope will eventually take in the continents they represent.
The three made the pact at talks ahead of an informal World Trade Organization (WTO) meeting in Rio de Janeiro.
The action is on a separate track from the WTO's continuing efforts to free trade between rich and poor nations.
"The final objective of our three countries is a free trade agreement," India's external affairs minister said."
