Economic growth is usually measured in percentage terms. There are good reasons for that. If they can keep the growth rate, the Chinese economy will be larger than the US in about 10 or 15 years.
China's is still a developing economy and they have a lot of ways to increase productivity compared to the US. They are also at a leading edge in many technologies of the future so they do not need to spend as much as other developing countries to purchase them from abroad.
China's growth rate may slow down but it will continue to be faster than the US rate for many years.
US Dollar is the world's reserve currency. If US dollar becomes less strong in the future, the size of US economy may not be as large in relative term anymore. The petrodollar system may not be as powerful when renewables are more important. Perhaps China also considers this when they push so hard for renewables.
