Are there examples of affirmative action (or equivalent) being applied to White groups?

In Does the VRA require drawing districts for white people in majority-minority states? it was asked if the Voting Rights Act could be applied to white minorities any time soon and the answer seems to be no. This got me curious - are there any examples (in the US or some other country) where affirmative action was applied to a White minority? A hypothetical example would include White students in China being granted free tuition because they’re underrepresented in local universities.

The definition of "White" for me is the same as in the US Census: "having origins in any of the original peoples of Europe, the Middle East or North Africa."
