yes you are right but diffrences between turkey and china is that china is communists and turkiye is democracy
Communism and Democracy has nothing to do with joining a block, Pakistan which is a Democracy before Mushraff and even after him (when ever he leaves) will be with Communist China.
People or rather a nation(s) join a block when they know they can gain some benefits mostly power in the region, and backed by a major player (Boss), to cover them.
The Middle Eastern (Puppet) regimes are infront of you as an example, they aren't a Democracy, and still in US block "Influence".
