Fokienia foliage does not have the thick fleshy texture of Thujopsis. Also, not so easy but may be usable, the side leaves on Fokienia tend to be slightly longer than the facial leaves, whereas in Thujopsis they are about the same length.

The cones are very different:

For more info, check the Flora of China accounts.
