Sure, its possible that they place "greater emphasis on academic education" etc., but then you have to ask yourself what is the reason behind this.
As an Asian American who has had good academic success, my best guess is its socioeconomic. Asians who came to the US in the 70s - 80s often were highly educated, upper middle class, and they had resources to raise their kids towards academic success. They certainly faced some struggles, but were not socially disadvantaged in the way that other minority groups in the US have been.
You may not have meant it this way, but your post reads like a racist dog whistle.
