2.1 Geoeconomic Characteristics of Central Asia

Central Asia's strategic position at the crossroads of Eurasia grants it substantial geopolitical and economic significance. Rich in natural resources, including oil, gas, and uranium, the region is a key player in global trade and supply chains (Pomfret, 2019). However, underdeveloped infrastructure and fragmented networks hinder its full potential, creating a dependency on external investments to modernize transport systems and improve connectivity.

2.1.1 Geographical Advantages and Challenges of the Eurasian Land Economic Belt

Geographical Advantages and Economic Potential

Central Asia serves as a critical logistical hub connecting East Asia, South Asia, and Europe, making it an essential component of the Eurasian Land Economic Belt. Its strategic location offers vast potential for trade and logistics, augmented by abundant natural resources. For instance, Kazakhstan holds approximately 3% of the world’s proven oil reserves, alongside substantial deposits of natural gas, uranium, and minerals, reinforcing its role in global energy supply chains (World Bank, 2021).

The region's strategic importance is exemplified by the China-Europe Railway Express, which facilitated 40% of Eurasian land trade by 2021. This network provides a cost-effective alternative to maritime shipping, reducing transit times between Chinese and European markets from 45 to 15–20 days (China State Railway Group, 2021). The railway's importance has grown in the post-pandemic era, where disruptions to global logistics have increased demand for resilient land-based routes.
