It is quite some time since Nawaz Sharif made a foreign trip.
It may be the time Nawaz Sharif is planning a foreign trip. His normal place of residence is out of Pakistan. Here comes once a while to visit to see what is going on over here. Of course, he has a love for the place which provides him money supply.
Foreign Ministry which directly reports to him since he is also foreign minister of the country must be contacting foreign governments to arrange a foreign visit. Obviously that obscured country will be which you may have never heared.
If nothing else he would like to visit London. He also enjoys his stay in his Mayfair apartments. So far we have not heard any plan of his foreign trip that is surprising.
