It turns out that economic productivity is not tied to ethnicity or where you are from - fundamentally racist notions - but to how productive you are.
Also the Chinese immigrants in question, like many others, usually immigrate seeking a better life, it's a strong self-selection filter. Middle Eastern immigrants of last 10-15 years in Europe are refugees, displaced by wars; they did not choose Denmark (or other Western European countries) because they planned to integrate and to prosper there, they ran there to merely stay alive. They need a lot of help adapting. Even if they are very willing to work, they may lack the knowledge required for gainful employment, and there are only so many dish-washing and trash-disposal jobs.
Those who adapt can make it big; consider people like Freddie Mercury or Nassim Taleb.
It is about race, and here is a commenter saying it explicitly, while you know others resort to dog whistles and other workarounds.

The problem with immigration isn't immigrants, it's racists. Immigration has never caused me any problem at all - it's added a lot to my life and my communities, in fact - and I've lived around many immigrants.
> Chinese immigrants are usually an economic boost
Chinese immigrants were hated and discriminated against for much of US history, going back over a century. You could hardly pick a worse example for your claim.
The US is built by uneducated immigrants - including from China - who came to the land of freedom and opportunity. China was a land of extreme poverty and illiteracy for much of US history (something Western countries had a hand in causing, and I'm very glad for people there that they have so much more prosperity now).
(However, the most prosperous Chinese people are in the democratic areas, Taiwan and, until recently, Hong Kong. It's freedom and democracy, not culture and language that matter. Give people freedom and they prosper.)
It's all just stuff fabricated by racists to rationalize their prejudices. Look at the horrors Europe has inflicted on itself and the world due to these prejudices and rationalizations - the most destructive events in human history. Enough.
Racism is the problem.
Immigrants everywhere come with a language barrier. If you live in the US, very probably your ancestors did. It's the same with every first generation from everywhere.
And then their children turn out to be some of the most productive and contributory to a nation (in my experience), even despite some of the headwinds.
Sorry, I don't buy that argument re: second generation. I've lived and seen it. Perhaps my lived experience isn't representative but I don't see second generation citizens turning to crime or radicalisation in huge numbers. I see them at work, and looking after their families. I fear the brush you are using is so broad as to, sorry, be useless.
"The study has faced criticism over its methodology, as it only studied rape convictions in Sweden. Experts point to the fact that just a small proportion of rapes in the country are reported to the authorities. Jerzy Sarnecki, a criminologist at Stockholm University, dismissed the study as “meaningless” as it only examined figures for convicted rape. “They’ve only looked at convicted people, and they make up a fraction of all rapists,” he told Swedish broadcaster SVT."
Even ignoring the above, I can think of many reasons, statistical and otherwise for the apparent difference. Perhaps you should try using your brain matter to do the same rather than just posting random links.
I repeat: I don't see second generation citizens turning to crime or radicalisation in huge numbers.
They actually go lots of places. How are there so many refugees in the US (a good thing)? Canada and Mexico aren't places producing a lot of them.
It's a major issue of international law, as people who are anti-immigrants try to insist refugees stay in nearby countries.
