Cpec : a question mark for some people

Trade between Pakistan and china has increased to $ 16 billion according to economic survey 2014-15. The share of China in Pakistan's trade has picked up from 4 to 9 percent in one year. The most recent project in this case is the construction of Pak-China economic corridor.
All lot of people raised questions about it like, will it be helpful for Pakistan's economy ? Effects on other countries ? And most important the effect on Pakistan's defensive strategies ?

Cpec is 3218 kilometres long route consists of railways, highways and pipelines. It will be completed in several years. The cost of this project is expected $ 75 billion.
There are two phases , the first is to complete gawadar airport and development of gawadar port and second is the expension of krakoram highway.
If we take a look on the effects of this project then we can see that it can both helpful and not helpful for Pakistan.

Pakistan's economy was not too good for last several year but it is still better than nothing. There can be more economic opportunities for Pakistan and China with the construction of cpec. This route providing China a short way to trade through gawadar port. Over $ 33 billion worth energy infrastructure would be constructed. Cpec will also increase the annual GDP of Pakistan.

According to defensive strategies and army protocol, both countries can have military alliance. Both countries have almost same rivals so they can work on this kind of problems.
But on the other hand, a lot of people think that Pakistan is giving a simple route to China and it can be dangerous. Chinese military can have a passage to come in Pakistan.
CONCLUSION :
Both countries are working on this project for their specific reasons and it will be beneficial for both countries and people can do nothing about what they think but they can hope for the best.
