The Gobi Desert. On the assumption that the question was logical, ,we are looking for a city, not a dessert! Looking at a map, there doesn't seem to be a significant city at that location. There is a fairly smally town called Bayan Nuru close to those co-ordinates. The Gobi Dessert stretches northwards from that area.
If you are asking about what country is it, that is in the north part of CHINA.
Between the Gobi Desert in Mongolia and near Gansu. I'm not too sure, but I think it's part of the same desert that belongs to the Inner Mongolia.
