The present study is aimed to provide analytical review of Pak-China strategic cooperation starting from 1950 to 2017. Pakistan started to establish her strategic relations with the outer world soon after her independence in 1947 in order to maintain balance of power in the region. Bilateral ties remained very encouraging from the beginning of Pak-China relations. However, bilateral ties touch its heights in the decade of 1960s. After 1960s, bilateral relation turned to diplomatic relations because of changing world scenario i.e. cold war, terrorism, One China Policy and change of world order. Still China helped Pakistan financially, technologically and assisted in developing nuclear program. In 21st century, relations became stronger of and both the nations started helping each other to materialize their goals in diverse fields. One such example is the implementation of (China – Pakistan Economic Corridor) CPEC which is expected to change the fate of both the countries in future.
