I think this part is pretty moot. The high tech stuff like the fighters and stealth frigates, and subs, etc. will never be allowed to go to China for exercise by the manufacturing countries. Currently, SAF has many unofficial high level exchange with the PLA. U read the recent scandal where the SAF pay for english lessons for PLA officers who are on exchange here. They have access to our bases, weapons, manuals etc. I am sure their hackers have already gone into the MINDEATH data base and access whatever they want. The Terrex has already been stripped bare for them. Plus so many PRC shitizens working in ST, and other defence related companies. If they want to know the performance of the Leopard AMAPs applique armour, I think they already found it out. I think the technology level that the SAF has is known to the Chinese quite well.
