The assessment of the writer is bang on correct. Pakistan has a lot to gain from this trade compared to India.
However, they have to do a climb down on the issue repeal of 370 in Kashmir. India wouldn’t back off hence the ball in their court. If they back off on this demand then India has no issues.
Trade won't have immediate payoff. it will help in the long run. that is a bigger problem given the scale of the issues facing the Pakistani economy
