There might be some missing context here. China and the US are not experiencing growth and development at the same rate at the same time.

In the US, everyone that has access to electricity has had it for decades.

In China, the first year where 100% of the population has had access to electricity is 2013, according to the World Bank.

China is also putting its middle class into automobiles almost a century later than the US did, and they’re almost entirely skipping internal combustion. The US has basically no urgency to replace internal combustion as they have a well-established supply of oil.
