India is ready to offer incentives to ensure Tesla Inc's cost of production would be less than in China if the carmaker commits to making its electric vehicles in the south Asian country, transport minister Nitin Gadkari told Reuters.

Gadkari's pitch comes weeks after billionaire Elon Musk's Tesla registered a company in India in a step towards entering the country, possibly as soon as mid-2021. Sources familiar with the matter have said Tesla plans to start by importing and selling its Model 3 electric sedan in India.

"Rather than assembling (the cars) in India they should make the entire product in the country by hiring local vendors. Then we can give higher concessions," Gadkari said in an interview, without giving details of what incentives would be on offer.

"The government will make sure the production cost for Tesla will be the lowest when compared with the world, even China, when they start manufacturing their cars in India. We will assure that," he said.

India wants to boost local manufacturing of electric vehicles (EVs), batteries and other components to cut costly imports and curb pollution in its major cities.
