"they" being the CCP, or high-net-worth Chinese nationals attempting to get their money out of China?
Because if the latter, then the CCP is not going to give a monkey's what happens to that property. The CCP has been trying to stop rich Chinese from investing outside China for years now.
I'm no expert, but I understood that those were more "diplomatic" investments. The ports in Sri Lanka, for example, are impractical and unused, their function fulfilled as soon as the deal was agreed.
