The question is, in spite of excellent relations with China since decades, why is that Sino-Pak trade languishes at just around $12 billion? Compare this with Sino-Indian trade which is presently at $60 billion
and slated to reach $100 billion by 2015
and $300 billion by 2018!
The only salvation is economic progress by trade with all its neighbors, leaving politics, ego and emotions aside.
As regards ties with the US of A, it all started out with them co-opting Pakistan into CENTO as part of an alliance against the Soviet Union. That faded away gradually. There was no need of SEATO and CENTO once the Soviet Union broke up with the result that Pakistan's importance fell a few notches where the US was concerned.
Then came Afghanistan and Pakistan was once again co-opted to help drive the Soviets out of Afghanistan. That accomplished, Pakistan's indispensability to America lost steam.
However, 9/11 saw the pendulum rise again when Pakistan joined America and the West in the so called WOT.
Now that 2014 is approaching, the question is, will America need Pakistan thereafter? If not it will most likely be dropped from Americas strategic calculus in Asia.
