The protocol is signed in New York on September 21 2017. They are supplemented with check points for commercial railway transit of special cargo and accompanying personnel - these are the ports of Aktau and Kuryk.
As previously explained to the Ministry of Foreign Affairs of Kazakhstan, the US side requested a change in the current transit route for special cargo to Afghanistan. The main material supply route for the US contingent in Afghanistan passes through Pakistan, however, due to military-political instability and existing differences in bilateral relations, the American side is working on an alternative route: from Azerbaijan through the Caspian Sea to the ports of Aktau and Kuryk and further by rail through Uzbekistan.
In Astana, it was noted that the protocol will have a positive impact on the development of the transit transportation system and will continue to develop the logistics infrastructure of Kazakhstan.
