To convince investors it is a serious player, the AAP has set up a seven-member committee to forge a policy manifesto, including former RBS India CEO Meera Sanyal, former Idea Cellular Managing Director Sanjeev Aga and noted economists.
That platform is likely to seek foreign direct investment (FDI) in infrastructure and financial services, favor a nationwide goods and services tax to cut business costs and bring in a uniform taxation regime, two sources with direct knowledge of the policy discussions said.
"We are not against FDI per se, we are not saying that FDI should not be in any sector, this is a decision that has to be taken on a sector by sector basis," Kejriwal said.
The party would not oppose partial privatizations, and it may suggest a roadmap to plug leakages in the delivery of subsidized grain, fuel and fertilizer, the sources said.
Kejriwal is opposed, however, to the entrance of foreign supermarket chains such as Wal-Mart into India, arguing it would be damaging for local jobs and farmers. The Indian government has allowed entry of foreign retailers into the country but has left it to state governments to implement the policy.

Kejriwal returned time and again in the interview to his mantra, fighting the rampant graft that sparked unprecedented protests and hunger strikes in 2011 and led to the creation of his party.
"Good economics is the outcome of honest politics," he said.
India was ranked 94th in a list of 177 countries on Transparency International's 2013 global corruption index, lower than China, South Africa and Brazil. The Congress party-led government has been rocked by spectacular corruption scandals, and foreign investors regularly complain about the need for "speed money" to get business done in the country.
One of Kejriwal's first actions in government was to encourage citizens to use cellphones to record government workers who demand bribes, then call a hotline to report them. Businesses in Delhi say the effect has been dramatic, with far fewer demands for gifts and money.
