Which other international conflicts has China resolved? The current Chinese state seems to be much better at fostering conflict (I.e. the ongoing Korean War) than resolving it.
So far, not much. Gaza is a good place to start. China wants more influence in the Middle East, and already owns or operates a large number of ports outside China.[1] Israel blockades the existing ports of Gaza. A China-run port in Gaza, protected by the PLAN, is a possibility.
It also assumes that the _US_ would allow a China-run port in Israel, which is so unlikely it might as well be impossible. Israel is a nuclear weapons state and such a close US ally that they basically have their own F-35 fighter jet variant.
"At least two-thirds of the world’s top 50 container ports are owned by the Chinese or supported by Chinese investments, up from roughly 20% a decade ago."[1]
