The article analyzes the interests of Saudi Arabia in the Central Asian region taking into account the internal modernization processes in the Kingdom and in the context of global geopolitical turbulence. It is proved that at the present stage Saudi Arabia makes a lot of efforts to gain a foothold in Central Asia as an influential player using its religious authority along with financial and economic instruments of influence. The emphasis is placed on the fact that with the coming to power of the young reformer King Mohammed bin Salman Saudi Arabia’s foreign policy in the Central Asian direction changed from religious identity to a pragmatic approach to interaction with the countries of the region. In this context, the Kingdom positions itself as an attractive economic and investment partner. It is emphasized that the main ideological competitor of Saudi Arabia in Central Asia is Iran whose regional activity alarms the Saudis and encourages the Kingdom’s leadership to develop measures to contain it. It is concluded that Saudi Arabia actively joined the geopolitical processes in Central Asia symbolizing a new stage of the “Big Game” and confidently tries to integrate into regional energy and transport and communication projects through its generous investment injections.
