The silk road project must be a success for China at this point, failure is not an option.
China has many problems. Please do not take me to be expert in China issues. I just worked there many years as engineer. I have job where I commission ports and cranes. When global economy was very good, I was in China constantly commissioning steel mill after steel mill. Very high quality, very expensive. Central government says they want steel. They pay.
Many of the steel mills I commissioned are shutdown with some only running for a few months. The shear amount of steel capacity in China is staggering. They cannot dump onto the global market illegally enough steel to keep them open. This is a MASSIVE problem for the central government as there are huge number of steel workers that have been guaranteed jobs but they have no real work to do. On top of this, look at their housing situation. In China, it is illegal for anyone to invest in companies. On paper, you cannot purchase stock or anything like that. It is only relatively recently that the Chinese citizen can invest in anything...and the only thing is in real estate.
You know how many people are pissed about the rich owning property in Canada, Europe, and the US and they do not do anything with it? Those are not the rich of China doing it. These are the people priced out of tier I, II, and III cities. Everyone must invest in real estate because it is the only way to form nest egg for the future. So this is why you see a city with enough hosing for 200k, and maybe 60K live there. To get married in China, you must purchase a home. It is fucking bad there. Like any city with decent job opportunities is like US silicon valley.
And these housing goes up very fast and very shitty quality. It is not unusual for a high rise from the late 90's to suddenly collapse. If you spend any time in China, it is not unusual for a high rise elevator to never work. It doesn't matter if the building is a piece of shit. You hold onto it and then you flip it in a couple of years. I would see brand new blocks go up incredibly fast and within 2 years, not see anyone actually move in (though the units get sold) and everything on the units is falling down. I would joke with coworker that Soviet era housing blocks aged better than Chinese buildings.
Historically, China has face civil war whenever the standard of living of the costs gets very much above the inland areas. That is happening again. You also have a lot of government corruption, a growing pollution crisis, and severe water shortages in the next couple of decades. I don't think the Chinese government is failing any time soon, but at the same time, I don't think they have the power projection that many Americans think.
