I don't think that /s is necessary. I think the years have proved that china's trade barrier has worked wonders for home grown businesses. Look at didi chuxing. Blindly aped uber and worth more than them now. On the other hand look at India's own uber competitor: ola. They're struggling almost as much as flipkart while uber thunders ahead.
But as an Indian consumer, I have happy that I have a choice and I believe in the long run the more open Indian market would prove more beneficial to local businesses.
Their market caps notwithstanding - Alibaba, Didi Kuaidi and Baidu are not global companies. India already has one of the largest global ad networks outside of Google i.e. InMobi and I believe over the next 20 years, you'll see much more truly global Internet companies started out of India vs. China.
Unfortunately most Chinese are not tech workers reaping in cash, they're consumers who have to make do with poorer quality local offerings like Baidu and Weibo.
Of course trade protectionism is good for the protected industries. That should be self-evident.
The more important question is whether the benefit to domestic industry offsets the harm to consumers. Traditional economics would say no and I'd be inclined to agree.
Amazon is years ahead in customer support and services. Yes. but in terms of products sold, I'd argue that they are mostly the same: made in China or southeast Asia.
