dear brother.
At the outset,I appreciate your piece and encourage you to continue to write extensively as it is now a hackneyed phrase" practice makes man perfect.But to me,some corrections to your piece would enhace its significance and quality.
I mean in the first three paragraphs you have repeatedly refering to the peaceful transition and China's growing ties with Afghanistan refrain.I think it is intolerable repetition.

Although,it is imperative to discuss them but it would have been far better if you had discussed the strategic gains China and this region will harvest from there smooth bilateral ties.How China can be instrumental in sustaining peace following the withdrwal of isaf and nato.But overall I rate it a good attempt.keep on writing and sharing.
