You have given me some good clues to follow up Masud.
We have to consider that some species may do well on arid, harsh landscapes such as you describe where other species may have different requirements. It could be the yellow leaved pine is lacking certain minerals which it needs, where Pinus roxburghii copes. I wouldn't discount Pinus strobus 'Aurea' due to possibly lacking what it needs in climatic as well as soil conditions but without good evidence we are stuck. There are many forms of Pinus strobus. Have you read the description of P. strobus? The habit does seem to fit!
Habit: Small to large tree up to over 60 m in its natural habitat. Trunk usually straight and tapering, crown conic, broadening with age, becoming irregularly round-topped, sometimes developing heavy branches. Branch ends often erect with foliage in dense masses.
Could the description of the cones fit your tree? I think it could, given the variants and variation in size.
Cones: Solitary or clustered, pendulous, with long recurved stalks 2-3 cm, narrowly cylindric, often curved, tapering towards the tip, 7-20 cm long, 3-7 cm wide when open, light yellowish brown, very resinous, maturing in 2 years, shedding seeds and falling soon after. Cone scales thin, flexible, exposed end rounded, umbo smooth, pointing forward except near base. Usually a few basal scales reflexed.
I may have confused you with my search terms, by searching "eastern" I was hoping to get a location in the eastern part of what is now the only part called Pakistan, when I was at school there was an east and a west Pakistan but I am aware of the name change to Bangladesh.
The whole world is seemingly being ravaged, some places as you note are at real risk, populations continue to rise while the sustaining planet is depleted.
