Japan had a larger GDP per capita than the US from 1987 until 2000.
Inflation adjusted their GDP was nearly as large in 1995 as China's is today. They did that with 1/11th the population. China will never accomplish something that dramatic economically.
Japan held a lot more influence over the US at the time precisely because we were allies. China will never be allowed to acquire large numbers of important US companies (and vice versa), because we're unlikely to ever be allies. Japan's holdings of the US national debt back then as a % were also far greater than China's position is today.
In 1991, it was Japanese billionaires dominating the global richest 50 list. Taikichiro Mori and Yoshiaki Tsutsumi were the two richest people in the world, at $15b and $14b. That's nothing like what is occurring today, American billionaires are dominant.
In the late 1980s and early 1990s, it was the Japanese corporate giants that ruled the global economy. Today it's American corporate giants by a large margin. China's giants mostly can't leave their own borders and never will. The regressive command economy straight-jacket - mixed with political doctrine-based restraints - that their companies are permanently ruled by, won't allow it.
China's leverage today is not orders of magnitude greater than Japan at its economic peak. Asia as an example was far poorer across the board in 1985-1995 than it is today, Japan towered over Asia economically in a way China never will. In 1985, South Korea's GDP per capita was 20% that of Japan; China was 2.5% that of Japan; and so on.
