Agree with that. It was really stupid of GoI to ban Chinese firms. There are other ways of ensuring that data integrity exists. And you cant talk about being friends with China and ban their companies at the same time. That is hollow speak.
I think it was more out of pressure from domestic and Western telecom lobby. Companies like Bharti, Nokia, Motorola and Siemens are currently the leaders in the space and they dont want Huawei to capture market share at their cost. And Huawei and ZTE with their low costs and comparable quality are very much going to do just that.
Ultimately India should benefit as well similar to how China benefited from Joint Ventures with overseas firms on various projects. As mention by the others it will also show Western firms they can always have the cake and eat it too.
