I think this is a misconception. Chinese have a huge amount of tech which is sourceable from China. However, Chinese will not share this technology with India but they will rather disrupt local players. India should focus on building domestic equivalents to large Chinese players. I wouldn’t write them off as you suggest. India should invest in the latest lithographic machines and chip manufacturing processes.Not likely to happen that India will allow a huge Chinese investment in India, until the Chinese completely disengage at all of LAC.
Moreover, Chinese have nothing to offer. They have stolen tech and poor quality products which are cheap but last only three years.
