I don't know. Seems like a loss for them since they stand to gain big financial incentives whenever both teams clash in India though I could be wrong. Them succumbing to BCCI and ICC proves that they aren't on an equal plane.
Anyway, I am just glad to see this entire mess getting resolved as expected and am looking forward to both teams clashing in the future.
If India visits Pakistan for the Champions trophy, then at the most the PCB may gain a few million USD in terms of ticket sales and the Pakistani economy may get a slight boost in terms of hotel bookings and others. But that is minuscule when compared to the $34.51 million worth of funds that the PCB will receive every year from the ICC. The main point here is that same rules are applicable for both the BCCI and the PCB. India doesn't need to visit Pakistan, and similarly Pakistan don't need to visit India.
India not visiting Pakistan is just because they never want to give any economical advantage to them in any case as mentioned if we have Indian cricket team in any country it's good for them and their economy but in case of Pakistan it's never been had any impact even Australians are facing loses due to low sale of tickets and other things related to them.
But, now ICC ended this debate and all problem with a good decision which is surely helpful for Pakistan because now they can claim win-win for them, but surely Indian are feeling not comfortable even they are having no lost with this decision as well we have two events for Pakistan and two for India in next few years.
