As long as it's made by a Chinese and not by any western developer. I do not expect them to do our side without modern-day politics and some real-world history. If it's done today, it's going to be more AC shadows than Ghost in Tsushima. There will be no respect for the culture or people at hand. But that's difficult on its own since that Fallout ain't following real-world history. China in the Fallout series is like Cold War-era China but no one ever left the Cold War and instead just evolved further into it.
But what if there is a twist? Every thing we know about China in Fallout is through distorted via propaganda. It is like how China today is villainized through the 1.6 billion dollar counter disinformation bill. If China is truly that bad then why are there Chinese sympathizers of non-Chinese ethnicities in the Appalachians? These are interesting things to explore.
