Trump did much better with foreign-born Asians than US-born Asians, especially those with low English proficiency levels. That accounts for the slight swing towards Trump among SOME Asian ethnic groups (mostly Vietnamese-Americans).
Of course, Biden still got the overwhelming majority of the Asian vote in CA (74%) and nationwide (68%).
How ironic is this? That Donald Trump, who talked about "s***hole countries", who made demands for America to "Build the Wall", who implemented an immigration ban on Muslim countries, who introduced a greatly expanded "family separation" policy, who made negative comments about a Hispanic judge and a Muslim Gold Star family, who talked about "his African-American"...did better with nonwhite voters than in 2016 and posted the best performance for a Republican among them in years? And the "slight" swing towards Trump translated into a much more considerable one downballot, with the victories of Young Kim and Michelle Steel.
Among English speakers, there might be people to counter this, while they can fully understand the context of what he's saying. In foreign language, it's maybe done through a translator who may tone down some of the crazy or the visceral parts so they don't see it. That's my interpretation.
