Both Roadside Picnic from Russia and the Remembrance of Earth's Past trilogy from China have made me interested in Science Fiction from non-western cultures. There's a freshness of view that's hard to describe.

Then definitely track down Macmillan's Best of Soviet Science Fiction series:

Think Roadside Picnic x 100, because that's the quantity of really excellent science fiction stories and ideas you can expect.

A free (but bad) translation of 'Self Discovery' by Vladimir Savchenko is available if you search. I used this, together with my own physical copy, to make a proper ebook - let me know if you want a copy; I can't locate it at this moment...

And, in my opinion, the finest science fiction short story ever written (apologies to Asimov's Nightfall and Godwin's The Cold Equations): Nine Minutes, by Genrikh Altov https://www.altshuller.ru/world/eng/science-fiction4.asp

Not sure if you consider him non-Western or not but if you haven't read him try Stanislaw Lem.
