Some recent exchange of visits by General Pervez Musharraf, and more recently by President Zardari and Prime MInister Gilani, Moscow too seems keen to respond with warmth and eager to help Pakistan some of its complex problems. A good augury indeed. World over foreign policies of any country, is designed to serve that country’s national interest.
