Why are you even shocked shreya lifesciences for example was literally named in that news article about indian firms trading with russia. They were dhandomaxxing by buying gpus from malaysia and sending it to roos.
Sanctions will effect this rerouting business because the OEMs will not deal with a sanctioned entity.
But if for example lokesh machines is the OEM by itself it can double down on sales to russia... cause russia literally has thousands of crores of rupees sitting in Indian banks.
