This chapter focuses on infrastructure connectivity issues that are required for providing efficient service links between production blocs. It argues that after enjoying a rich history of about 1,600 years, the Silk Roads (land connectivity) went into disrepair. Now, for various reasons, land connectivity is once again making a comeback in Asia. First, is the growing importance of supply chain trade or parts and component trade which require efficient service links. The second is the ‘Go West’ policy and the ‘One Belt, One Road’ policy in China. The third is the opening of Myanmar, the node between SA and EA. This chapter also reviews bilateral, regional, and Asia-wide efforts to revive land connectivity including the ASEAN–India Connectivity projects and the recently initiated Bangladesh–China–India–Myanmar Economic Corridor. The chapter then proposes several new Trans-Himalayan Economic Corridors for seamless Pan-Asian connectivity between South Asia, Central Asia, and East Asia.
