The fault lies not so much in systems as it does in people. Certainly some systems are a better "fit" for people than other systems, but to say that having a 5 year plan or not having a 5 year plan is going to be the key to success or failure is incorrect.

Even more than how they are incentivized, WHO the people are you have working on something is the key to its success or failure. A team of uninterested geniuses will be as useless as a team of diligent dullards, and in either case, there is a high probability of failure for your project. It won't really matter how you organize either of those teams to get the job done.

The Chinese gov. is mostly centrally planning strategically, i.e. with investments, loans, subsidies, de-facto monopoly rights - which is another thing entirely.

In some ways, what the Chinese are doing is kind of like what Japan, S. Korea and even Europe did after the war.

But it's likely they are heading into a 'different stage' now where that doesn't work so well.

Also, Foxconn is Taiwanese, worth noting.

On the other hand Communist China seems to have gotten better at planning over time. (What you do you get good at)

'No plan' would describe US industrial policy since Reagan.

Small nations that have stayed with old-school communism and are mired in poverty - North Korea and Cuba at this point - have been almost totally isolated from the rest of the world for decades, unable to trade with large, obvious, prosperous neighbors. Is it the five year plan, or the sanctions?

The USSR eventually failed, but they did improve a great deal over the economic situation Russia was in at the time of the revolution. And honestly, there's no guarantee that a financial collapse won't wipe out the world of western capitalism, either. The US came perilously close to that in 2008.
