I did say those members would be before an Elite member on DL or KLM/FB.
But now what you say list or not Skyteam elites will be in-front of non skyteam elites. I have even asked such a question a year or so ago. And the policy is no different from say DL elite member flying CI or CZ.

They wont be on the list on your words but they will still have higher priority than non members or members who are non elite. But from CI's interpretation from their US and Taipei office this is generally accepted. Just like i was allowed to sit in Economy comfort due to my Elite plus membership with KLM but non elites and others were made to sit in the back with the flight not being completely full but not that empty in economy section. The 3 other passengers in Economy comfort with me were all like Elite KLM gold members.

Geez some superiority complex these DL members have...

When asked will the Delta members get an upgrade on Asian carriers i never heard anyone say they are not on the list but just far far back in the line which is right.
But the other way round its not even on the list yet its no different from the other situation i just mentioned.(This excludes the few examples stated before like the FB preference and the connecting China co-operation).
