My observations to the brighter side and a critic view.
A million dollars question by you indeed though it looks like route is allowed only against use of Pakistan transport within Pakistan territory as a sign of economic benefits, as per contract that seems good picture from transporters to labour.
Such contract will help ease tension between these 3 countries and will be helpful economically to the people involved especially transport/labour class.
So also shows the sign from Pakistan side that we are indeed peace loving nation and wants to maintain a good relationships with all.
Critic view. ......
While on other hand there are doubts like are we going to give a route to more terrorism as no one can guarantee a fool proof security due to the current condition of security and stretched legs of Military yet will result in more burden on Military.
So also the question should be raised about such sudden change in mood towards one that never miss a chance to defame Pakistan and seems like the love of money in steel business and the mango/sari diplomacy.
Not to go long back in history but should have a look at recent blames upon Pakistan and all those observations and insecurity of defence purchases though there is a list to discuss.
Furthermore, recently one of Indian state refused to provide security to our cricket team for a match against India due to protests of local reasoning their martyrs which clearly indicates the blame upon Pakistan and our current leadership is not aware what happened herein and who did, how innocent. We remember our martyrs and confessions of criminals as well.
India has been expressing her intentions for Pakistan that will never miss a chance to destabilise us yet government is busy signing contracts with the same country behind the closed doors even without bringing in public knowledge or parliament/assembly but wait, it is the same government that came into power after mandate givenby Pakistanis.
What is the use of Sher Khan Bandar to Pakistan for trade with Tajikistan after the assurance of Afghan Government yet herself fighting a war for internal security but guarantees us.
On condition by Afghanistan to include India, see who demands, the Afghanistan which never miss a chance to blame Pakistan yet exports terrorism to our lands. Even US admits the Indian business of creating problems for Pakistan through Afghanistan but Afghan Government never expressed that to India in favour Pakistan.
We also need to keep in mind that there are elements in Afghanistan that dislike India and current Afghan government and the same can create problems for us just for favouring their enemies and taking sides and it would be wise to not make more enemies yet these 2 are enough for the moment.
Or
It is the outburst against all the efforts and sacrifices of Military for peace and CEPEC that India openly opposed from day first. Here, not to forget that to the most extent, it was the efforts, sacrifices and assurance of Military that made CPEC possible but seems like NS couldn't stop that though favoured his business partners.
There could be more to add in brighter side of such contract to prove that it carries the weight but should be beneficial in practical and not like to fool people and to take political advantage. Also these critic views can be added with more realities and could be rebutted by NS government but on solid grounds other than diplomatic statements and never fulfilling promises.
