China spends more on internal security than defence. Obviously that’s not remotely all PAP funding, but I don’t think they are as badly funded as most seem to think.With that being said, the PAP also likely doesn’t have a budget as big as the PLA, taking into account that they don’t need big ticket items. So proportional to their different roles, the PAP seems to get more new personnel equipment than the PLA.
In addition, they still get PLA surplus at discount or zero rates for the bulk of their armament needs, thus leaving them with more budget to play around with fancy equipment and weapons.
The PLA will have its own dedicated units for testing how foreign weapons and kit compares to their own, and will have very different demands and priorities compared to the PAP.
