Abstract No state can live in isolation as individuals cannot live in isolation, they interact with each other. Similarly, the states cannot live in isolation, and they will have to interact with other states, International Organizations, and other entities that perform the starring role in World affairs. A large part of financial and technical assistance needs that a country gets from outside. Similarly, issues of peace, security, and stability in international governance cannot be encouraged unless nations work together, discuss their issues, and decide about the tactics and policies to deal with the status quo. Pakistan and Saudi Arab have long good relations, which have been strengthened by growing economic cooperation between the two partners and the desire to intensify their strategic commitment. Pakistan views Saudi Arabia not only as an infrastructure and economic development plan but as well as a key initiative with wide-ranging implications for the country’s domestic economy and social makeup and a potential “game-changer” in the regional position. All of these suggest that the already deep Saudi-Pakistan military and strategic bond will continue to be robust. In the given context, the target of my study and research will be to examine the historical process in the gradual culmination of Pak- Saudi relations into a broad-based partnership, the present nature of liaison between the two countries, and the expectations it holds in the wake of shifting world order. Pakistan is an important Muslim country, and it dominates a very important geostrategic location. While on the other hand, Saudi Arabia rising economic, military, and technological power has remained the focus of attention for regional and global political actors. Both countries' foreign policies in the new century will be increasingly determined by their domestic, economic, and political conditions. Both must acknowledge that internal stability is the key to a country’s security and development
