The G20 promised strong, practical measures to reduce the global average cost of transferring remittances to 5 percent, which goes up sometimes as high as 10 percent.

The communique also promised to raise global growth to deliver better living standards and quality jobs for people across the world to ensure financial inclusion. It specifically set a target of raising the output of G20 members by around 2.1 percent by 2018 and the necessary steps towards achieving this.

India said this was significant. "We have $2 trillion of extra global economic growth, which will happen because of this 2 percent growth rate, that we are talking about. I think India would benefit, but India will also contribute," Prabhu said.

"India will contribute because India’s growth rate will definitely be upwards of 6 percent, and definitely India will benefit because when the global markets open up, we will also get a significant part of that as our share of the global trade," he said.

"Just to add, the Brisbane Action Plan mentions two emerging markets as growing strongly - China and India. Only two by name," said Usha Titus, who was the deputy Sherpa giving key inputs specifically on financial matters.

Prime Minister Modi had also made a strong pitch for energy security and finding alternative solutions. "Our prime minister mentioned that we should create a global centre for dealing with renewable energy to find solutions and everything. It was very widely welcomed including by those who are not part of the G20, like Jeffrey Sachs and others who have been saying that this is an excellent idea that we have done," Prabhu said.

Indian interlocutors said another issue that has become a central theme for G20, thanks to India, is employment. There was also some movement forward in raising the target of 25 percent jobs for women.

"This is very significant because you have noticed that in the last several decades we could have unprecedented growth in global output but absolutely no relationship with employment. So, this has been a very significant demand, significant contribution India has made for her own interest and also for others," Akbaruddin said.
