The scale of China can't be matched by any other single country. But considering India's past and present, this is the largest ever e-commerce sale pulled off by it's own local company which is a giant leap in it's struggling economy.
To me, what's happening in India e-commerce growth is just extension or expansion of Amazon model, on a bigger scale perhaps.
But for Alibaba, it is truly revolutionary if you look at how much of their Tmall sales percentage(relative to taobao) in that $5.78 billion sales, it is truly manufacturer-to-consumer.
