That singled out one concept might not be chinese only that's true. But Zhuangzi and his particular self contained abstraction of '无为' https://en.wikipedia.org/wiki/Wu_wei https://en.wikipedia.org/wiki/Wu_wei is quite characteristic and focuses much on integration (so it shouldn't be taken out and interpreted alone). Maybe there are similar philosophical works but I doubt it would be identical.
