Mukesh Ambani outlined the plan at the company's annual shareholders' meeting in Mumbai.

Reliance Industries Ltd. plans to take on the likes of Amazon.com Inc. and Walmart Inc.'s Flipkart Online Services Pvt. in retail by creating a platform that combines online and conventional shopping.

Billionaire Chairman Mukesh Ambani outlined the plan Thursday at the company's annual shareholders' meeting in Mumbai. The effort will involve the group's Reliance Retail Ltd. and Reliance Jio Infocomm Ltd. businesses, he said. The latter will also introduce a fiber-based broadband service Aug. 15.

Global retail powerhouses like Amazon and Walmart have been investing in India's retail industry, where e-commerce sales could more than double to $72 billion by 2022 from $32.7 billion in 2018, research firm eMarketer estimated. The retail-to-refining conglomerate is looking for growth in e-commerce after spending as much as 2.5 trillion rupees ($36.3 billion) in setting up mobile and fiber broadband infrastructure, Ambani said.

The platform will use augmented reality, holographs and virtual reality to create an "immersive shopping experience," Ambani said, without giving a timeline or financial targets. The service will be available to small merchants as well, enabling them to "do everything that large enterprises and large ecommerce players are able to do."

Walmart, the world's largest retailer, said in May it will acquire a 77 percent stake in Flipkart Group for $16 billion, leaving the remainder to Flipkart co-founder Binny Bansal and other shareholders.
