Read the post above.
The flows from Pakistan to India are to pay for the goods (through Hundi) smuggled into Pakistan from India, often through Karachi cartels (via UAE)...called as hundi remittances. It has been documented on this forum itself.
When the economist magazine EXPOSED this quite openly in BD case regarding countries like China (accounting as 1 dollar when its 10 dollar transaction and paying the difference through hundi), its not supposed to exist between India and Pakistan?
But basically BD does much more legal trade with India, thus the massive trade deficit exists officially above the ground. Only 100 million or so is "remitted" from BD to India (by Indian expats etc) unlike the 5 billion USD that BD illegals in India remit back to India:

So who are the parasites established by the neutral 3rd party?
And all these years we have had Indians like you bragging that BD needs very well paid Indian managers in their many thousands to run the country.
This report is complete nonsense as the same organisation said that India received over 4 billion US dollars from BD in 2012.
