Not only is it no use, but it's very counterproductive. It's hard to push for innovation locally as it's initially higher cost and lower quality so local companies are incentivized to continue to buy foreign. Without the customers to drive demand the top down initiatives invites corruption and money spent on it just goes into a bottomless black hole. By being sanctioned you have the foreign countries ensuring local companies can only by locally and are not able to bribe the foreign countries to circumvent.
