Jews have almost no historical presence in East Asia. They have accordingly had very few instances of persecution or segregation there.
Jewish persecution has been present pretty much everywhere else though, with the Jews persecuted looking largely like the majority within their host country.
You're probably familiar with Ashekanzi Jews, which are the European diaspora Jews who look ethnically white (where the majority is white), but there are Jews from middle eastern countries like Syria, Iran, Iraq, Jordan, Yemen, and Lebanon who look more similar to North Africans or Arabs than they do white people. This group of Jews typically got treated as second class citizens, being sectioned off from the rest of a city, taxed higher, forced out of jobs, and often forced to see their communities exiled or destroyed.
Beta Israel is a particularly interesting group of Ethiopian Jews who look like any other Ethiopians, which caused a reform in the who the larger Jewish community considers Jewish or not. This is cool, because it's a group that was discriminated against not only by their host community but by their own people.
The history of Jewish persecution globally is fascinating and worth investigating. The list of pogroms, expulsions, mass conversions, and attempted extermination campaigns is incredibly long, and is something that I have yet to find in any other group. This history is hugely relevant to Magneto, and is almost inseparable from his motivations. It also provides him with a huge moral flaw, which is that he propagates and often assists in similar campaigns to convert, expel, or exterminate non-Mutants. Whenever he is a hero character, it is in a Zionist capacity or as a skeptical assimilated citizen.
Also note that Genosha is geographically in the region Zionists were initially offered when they wanted to establish Israel.
