You do realize that there are sensible ways to prevent Chinese goods from entering the country, such as imposing duty? Or simply legislation to enforce quality?
You do realize that currency devaluation has many other massive negative spinoffs?
You do realize that there is an urgent need for manufacturing policy in India, with labour reforms etc.? It is not as simple as allowing the rupee to slide, slide, slide, and then celebrate that we will be unable to import any Chinese stuff. Of course, it is another matter that fossils like Mamata Bannerjee will block any kind of reforms.
We have mentioned all this earlier. The way you're talking is as though the rest of us here favour Chinese imports. If you are such a fan of currency devaluation, why do you crib when petrol prices go up? Even if you reduce the tax to zero, the next round of currency depreciation will increase costs even more.
