IMHO, since the basic infrastructure such as power plants and main roads is nearly built up, it is the high time to move to attract the investment from around the world. The concerns of the potential investors might have are:
1. the security and safety situation in Pakistan even though it has been improved a lot and still from time to time there are suicide bombs or terror attacks. Also, the tourism business is tremendously baffled because very few people dare to set foot in Pakistan which boasts wonderful natural and historic resources.
2. facilitate the ease of business to attract investments. Now Pakistan need more investments on manufacturing, tourism, and agriculture so that Pakistan can be more self-reliance and gradually start to increase exports to the rest of the worlds.
