India, Brazil and South Africa will back each others' claims for permanent seats on the United Nations Security Council, the Brazilian president says.
India and Brazil have shown an eagerness to work together
President Luiz Inacio Lula da Silva made his announcement at the end of a four-day visit to India.
The three nations have already agreed to work together to counter the trade policies of wealthier countries.
That project has received a new impetus - although it can hardly be seen as hailing the start of a new world order.
Nonetheless, from the perspective of Brazil, India and South Africa - as also from the point of view of several other poor countries - a definite attempt is being made to change the rules of the game as they exist now.
The idea of unifying the world's poor recorded its first success in September last year at the Cancun round of WTO negotiations - the trade talks collapsed because the developed and the developing countries failed to reach an agreement on issues like farm subsidies.
The Brazilian president said the issue still remains unresolved, as the US and the European Union continue to maintain farm subsidies.
He said it was important for countries like India, South Africa and Brazil to build on their unity and make the rich countries understand that dependence on them was a thing of the past.
There may be some more joint strategising in March this year, when officials from the three countries meet in Delhi as part of the recently formed India-Brazil-South Africa dialogue forum.
On a bilateral front, the visit of the Brazilian president has been a big success. Both countries are large and India and Brazil have a lot in common, including the scale of their socio-economic problems.
There is also immense scope for expanding bilateral trade.
While a preferential trade deal has been signed during this visit, more agreements are likely in the coming months in sectors like shipping, aviation, rural development, health care and science and technology.
