In my limited knowledge, this is what Pakistan can export.
1- Rather than Cotton, export end products. Like in Macy's if i can see so many garments from country like Bangladesh and Sri Lanka then why not Pakistan?
2- Apart from regular garments, stand encouraging insititutions to provide hign end fashion garments in South Asia. I know that Pakistan Garments designers and their dresses have good demand in India...I hope you can market the same in South Asia as well as the countries who have simillar dress sense.
3- Cement : This is the one item, i always here India always eager to import from Pakistan...I am not sure what is happenng....So guys, no one is denying to stop animosity with India or US or any one...But if you can keep economic relation away from the regular thing, then you can get good market from your end product of your materials in Soth Asia and Central Asia as well. Stop exporting raw material to any country..Rather enforce them to create infra in your own country and provide subsidized rate of raw material to them.
4- Encourage to show your nation as a tourist spots to your friendly nations...Tourism is another form of channel to earn foreign exhange...
