In June 2018，the Shanghai Cooperation Organization saw the first round of membership expansion. The joining of India and Pakistan added more meaning and alternatives to the economic cooperation within the SCO framework. At a time when the international order is fast changing and the world economy is undergoing profound adjustments，the SCO member states attach great importance to the stability of their national economy，and building a strategic planning system，optimizing economic policies，and strengthening macroeconomic policy coordination have become the reform priorities of all member states. Depending on the national conditions，different members have set forth different objectives，priorities and means of implementing the economic development strategies. Accordingly，the results achieved are not the same，especially the newly joined India and Pakistan. Based on the specific analysis of national economic strategies，plans and policies，this paper discusses the possible problems in the process of strategy implementation，with reference to the sustainability，systemicity，feasibility and execution of economic strategies.
