China is most definitely going to be spending that in a tit-for-tat arrangement, as hinted at by the spy stations.

Yes, China is already spending so much in much less developed/educated places, seemingly just for "goodwill" or at least to be in a good place once the US hegemony falls. The only reason they wouldn't do it in Cuba would be to avoid needlessly provoking the US, but I think they have a good excuse now (clearly US is the provocateur, they're only restoring some semblance of balance in the longer term).
