China has built at an even more aggressive pace and scale. It has built an unprecedented amount of infrastructure in an unbelievably short amount of time. That infrastructure will reach end-of-life all around the same time. It's likely going to end up as an infrastructure crisis at a level beyond what the US is suffering from now.
*I am not claiming that all Chinese construction is shoddy, but adherence to code in building is clearly a significant issue and the only way it won't have multiplying effects to cost are if the only goal was the economic activity of the construction process and not at all the constructed result of the process.
