^^^ only Russia needs to follow MCTR not us if it is manufactured in Russia it needs to be less than 300km if it is manufactured in India it can be however long it wants to be
Two points...
1) If MTCR to be followed than both Russia and India need to be followed. They cannot share any technology that gives more than 300 km or 500 kg payload. But I think the propulsion system is developed by DRDO, so MTCR restriction will not be a problem.
2) India may become a member of MTCR in coming years.
yeh bhi koi phuchne ki baat hey
