The SCO is not a military bloc. You can join this organization while remaining a member of NATO. Why should Türkiye leave NATO???
Hungary is a member of NATO and the EU, but also wants to be in the Organization of Turkic States.
Armenia - it is a member of the Russian military bloc CSTO, but at the same time it has become a strategic partner of the United States.
By the way, just a week after Washington announced this, China and Azerbaijan also announced a strategic partnership.
We (Azerbaijan) will become a full member of the SCO in the coming years (possibly in 2025).
Since the Europeans do not want to accept Turkey and Azerbaijan into the EU, we have every right to do what is beneficial to us.
What confuses you about the SCO?
