Methodologically, the qualitative study relies on primary data in terms of elite interviews and secondary sources such as journals articles. This theory-guided empirical research has identified two sets of challenges, internal and external, that the economic corridor faces. Broadly, the challenges range from economic slow- down, political instability, religious extremism and terrorism that have taken toll of Pakistani economy, society and the state. The paper has provided policy input in terms of urging Pakistani government to reform its educational system and correct political instability along with targeting all types of militant organizations. More- over, the study urges China to engage regional stakeholders in CPEC to realize regional and trans-regional connectivity to achieve economic integration of the market.展开更多
