As an old Chinese saying goes, maintaning moutains and rivers beats conquering them ( Da jiangshan rongyi, shou jiangshan nan)!
It is difficult for the US to MAINTAIN its top position in the world;
while it is RELATIVELY easy for China to play catch-up games!
The reason is obvious!
Just like a long-distance race, runners in the leading position in the course of the race frequently change faces!
Those who stick their heads out of the rank gain full exposure to the rest of the runners, thus vulnerable to the latter who can adapt far more flexible strategies to steal the show of the final lap!:P
