I watched the first episode the Sympathiser last week. It occurs to me that South Korea is the only Asian country that has produced significant modern-era (i.e. Cold War and later) espionage dramas that have been widely distributed in the West: these with the two Koreas as protagonists, of course. The only other Asia-focussed espionage dramas that spring to mind are a few with pre-WWII era plots involving Imperial Japan.
