The PLAN Marines could definately use a helicopter carrier of some sort. The Varyag could fufill that function once China has a more advanced indigenous carrier. As for other equipment, the PLAN Marines are pretty well off, but obviously their going to need more ampihbious capability. ATGMs are a big part of their arsenal because of the dangerousness of a Taiwanese counterattack on landing beaches (see the Taiwan MBT thread.)
I thnk the question for the PLAN Marines is do they want to become like the Royal Marines, a small elite ampibious force that can get ashore and conduct limited operations without much trouble or like the US Marine Corps, which is the world's biggest Marine Corps, operates MBTs and could crush the militaries of most of the worlds countries but is very tough to move around and deploy, and is not as...elite. That's the choice. I think that the PLAN Marine Corps will choose a combination of both, but more toward the Royal Marine option. China is large, so it's force must be big, but I don't think that it will have the capability to move lots of tanks all over the world and have its own air force any time soon, like the US Marines.
