I think it's due to China having many cities, many different resources and many possible trade partners. Losing trade output is too much of loss for them, and iirc AI doesn't care about stabaility when choosing civics. AI fanaticism of sticking to favourite civic depends on the leaderhead in question.but after some turns they switch back and became unstable, although Isolationism is favorite civic.
Japan loses little from Isolationism as Tokugawa is very averse to open borders and rarely offers them even with Pleased relations.
