It seems that the lifting of the American sanctions is not to materialize promptly, at least in the foreseeable future. Whenever

we are to get optimistic that they will be removed imminently, then this is the time that America is noticed as much determined not to do it. The renewing of them recently is but the good illustration of this.
Needless to say, the incumbent Sudanese government has been noticed as wasting much time and efforts in an endeavour to let the embargo to get lifted, but to no avail.
In this regard, there is a question that poses itself vehemently here; why is the government of Sudan very concerned to do it with America which in turn is utterly negligent of it?
It goes without saying that relations between countries are often mutually oriented, especially sisterly and friendly ones. In this concern, Sudan and China are but the true exemplification of this.
Because this kind of mutuality is almost lacking between America and Sudan, so the story should just end here.  As it turns its back to Sudan, so there is no way out for Sudan but to behave in a similar manner. History is full to the brim with incidents as such. Cuba and Iran are but only few instances to be mentioned here. Until recently, their relations with America were tense and much characterized with unlimited hatreds and hostilities.This situation continuous just like this for decades and decades. Then, all of a sudden changes happen. Now, all the three of them have been enjoining good relations mutually.
In conclusion, we can say this; Sudan should not busy itself very much with this America. As it has normalized its relations with Cuba and Iran unexpectedly and after a long time of a merciless embargo, so one day the same story will get repeated with Sudan, Allah willing.
