Opera is a public company. Almost all public companies have shareholders from all over the world, including China.
https://en.wikipedia.org/wiki/Opera_(company) has some details.
EDIT: that Wikipedia article says Opera is indeed a public company, but it's only indirectly publicly traded via a chain of parent companies.
While Opera might not be a Chinese company in the strictest definition, over 50% of Opera's shares are owned by their Chinese parent company, and by all accounts around 80% of the shares still seem to be in control of the Chinese conglomerate that owned Opera before it went public.
Since the CEO of Wikipedia is Egyptian born, would you define Wikipedia as Egyptian owned? Note that Egypt is a US backed dictatorship.
(Eg Google is controlled by its founders, who still have the majority of share voting rights and are in power as executives. But it's not majority owned by them anymore.)
