Well, according to your source it's a 11 billion USD increase from July 2013 to July 2016, and according to ministry of finance it's 13 billion increase from June 2013 to June 2016. It's a one month difference. Both could be right.
But it is important to note that approx. 40% borrowing wasn't spent on any development project, rather, it's spent on returning the previous loans. Also, the rest was also not spent on any revenue earning/ development project but on increasing the foreign currency reserves (although it is not mentioned anywhere, but we can safely assume due to significant import/ import balance, reduced remittances etc).
Also, some of the fresh loans have a grace period. So the impact of these loans will be visible after a couple of years when grace period will end.
