Pakistan has a lot of trade with Europe, close to 30% of our trade volume is with Europe. Pakistan enjoys GSP+ status for preferential trade with Europe. Europe means EU. EU means Nato countries as well, overlaps. Hence we absolutely do care. If Pakistan looses even 15% of its exports and there is no more IMF support, we will 200% default. Not to forget 21% trade volume with USA.

This is the achilles heel of China-Pakistan relationship.
If Pakistan is to become a independent actor, free to pursure its own interest, without external intervention, it cannot be economically dependent on the very same external powers who most likely to intervene.
From a purely geostrategical POV, Pakistans goals align less and less with the current hegemon and more and more with China.
Therefore its puzzling to discover that Pakistan-China relations are strongest in the field of defence and probably weakest in the economic realm.
If China had wanted to do so, it could become top destination for Pakistani exports. Which would make it much easier for both nations to pursure common goals, with little fear of western sanctioning.
That this is not the case, proves that Pakistan and China (vis a vis India) is trying to play a balanced game, not comitting entirely to either power centers. The problem is that Pakistan next door competitor; India, is also playing the same game, and with a much deeper experience in this field. To Pakistans disadvantage, India because of its geography and population size, is able to pursure independent policies without any significant sanctions from the west.
The solution to this problem is to play the book of Deng Xiao Ping; Keep low and bide your time.
Stay quiet and take defensive actions only when it really matters. Otherwise talk sweet to everybody and especially the current hegemon. Play optics while you build your strength in secret. Only reveal your strength in suprise moves, when it really matters. Most of all, diversify your economy and become more self suficient.
Xiao Ping had the luxury of CPC and Chinese discipline. In order to succed Pakistan also need cohesive and centralized political body in order to implement the aforementioned policies in the best manner.
