Since the beginning of the Russian-Ukraine conflict, the countries in Central Asia (CA) became acutely aware of the severe limitations related to their transportation routes. With heavy dependence on Moscow, CA countries decided to engage in diversification of their import- export channels. For Bishkek and Tashkent such attempts resulted in the renewed interest in advancing the China-Kyrgyzstan-Uzbekistan (CKU) railway project.

The EU wants to slash emissions from transport by 90 percent by 2050 by getting cargo off of CO2-emitting trucks and on to much cleaner railways and barges.
