Trump and our right-wing government is helping speed things along, but it's a bit of a stretch to claim they're eclipsing the US. It's more like we're fumbling the ball.
Moreover, China's economy is heavily dependent on the consumption of the goods they manufacture for other countries. As their own population demands better wages and living conditions they've been outsourcing basic manufacturing to places like Africa. They haven't got a good foundation to develop the systems, intellectual properties, research, and other things necessary to move beyond manufacturing. Things may be changing, but the sort of cultural change required for that effort is huge. Even with Trump's substantial effort to tear down the US as a world power it is not likely China will rise to even nearly the same level of dominance any time soon (decades out, if ever).
