Yes they(China) like and prefer to focus on trade and economical benefit, the war they had in the past taught them very harsh lessons so now they continue to build up so they never get that situation again, However, the technological advancement of China is simply unbeatable now. While they themselves don't have real combat experience, but through Pakistan they are able to test and validate their military tech, as proven last year in May 2025. Now they are able to hold anyone on their own, no help needed. Coordinations and strategic calculations and consultations are always happening to ensure regional stability and deterrence.
Now Turkiye and Pakistan will need to increase ownership and take on those additional responsibility of safeguarding the middle east (some countries have been badly damaged and war-torn like Libya, Syria, Iraq, Lebanon, Palestine etc) all due to the zion games in middle east. The rich GCC will need to provide, at the very minimum, the financial backing (it is in their interest too). If they don't, they may end up isolated and taken down by the zionists.
The zionists/west is not happy with this pact or with any hint or posturing that the muslim nations will get together, because it becomes an existential threat to them. They are doing everything they can to disrupt that and KSA is in the way/target because it happens to be largest in size and its the center of our faith due to Makkah and Madina. They are now trying best to destabilize it as its one of the richest in the region.
