Tibet/China is running Qinghai Hoh Xil in 2017

Yes, but one can regard them as fully inscribed, akin to the Vatican and Kiribati too.

Yes, I do agree, but Luxembourg used to have two tentative sites and we never know whether they'll recreate a new tentative list.

I would rather skip and forget about Daesh, 'cos there's no such a country. And it is not a special territory neither. This is just a jihadist militant fundamentalist group occupying part of Syrian and Iraqi territory. They also control part of Nigeria, Libya and Afghanistan. Do we want to legitimize it?

I wonder?? Never say "never"!
Luxembourg might decide to put a "Moselle Vinyard CL" on its T List as a transboundary nomination with Germany.
And surely Luxembourg has a few Beech Forests which it could add to all the others queuing up for addition to the existing Inscription!!
And what about Iron Ore Mining??

Agree with Solivagant on this one! Don't underestimate the ressourcefulness of countries to find ways to piggyback on other nominations. Looking forward to learning more about the well-known Albanian beech forests.

Joke aside, to add to Solivagant's list, Luxembourg could join a "Celtic oppida" serial nomination with France, Germany, etc etc - the site of Titelberg in Southern Luxembourg was apparently the capital of the Treveri people before the Roman conquest (based on Wikipedia):

Point taken. Added Luxemburg and Kiribati, but not Vatican or San Marino.

Perhaps Khuft "knows something"!?
I am afraid that "Oppida" had not previously impinged a great deal on my consciousness.
I found this to be an interesting document which describes (with reference to UNESCO and ICOMOS) both "Oppida" and the cultural landscapes within which they are situated

I cant find an existing WHS which makes an issue of any "Oppidum" remains and the current T List doesn't seem to have (yet!!) picked up on this potentially fruitful source of future nominations. A Google search only identified this Serbian T list entry which includes an "Oppidum" as a very minor part -
http://whc.unesco.org/en/tentativelists/5540/

The Wiki article includes a list of Oppida across Europe

I will never considered Qinghai as part of Tibet. It maybe under Tibetan culture influence zone. But Qinghai had always been struggled to be separate from both Tibet and Han China.

Probably you're right but I found it while searching about this proposal: http://whc.unesco.org/en/tentativelists/5991/, https://en.wikipedia.org/wiki/Qinghai, https://en.wikipedia.org/wiki/Tibetan_Plateau

Haha! No, unfortunately I don't! I have personal connections to Luxembourg and was disappointed when Vianden got kicked out a few years ago. So at that time I googled a bit for other sites that could be suitable and came across Titelberg - and from there to the broader Celtic oppida theme.

Heh, compared to some of the (vineyard) CLs out there, a Germany/Luxembourg extension to the Upper Middle Rhine wouldn't look so bad. Not that I condone it of course with viticulture and rivers with castles being pretty well represented... But I do find it more beautiful than the Rhine itself even.

Celtic Oppida would actually be of interest. Having come across several in southern France and Germany, I was thinking about how important the Celtic migration was to Central Europe and how few continental (purely) Celtic sites there are.

Actually, there is such an attempt fleshing out, however without Luxemburg (yet).

Hahaha, of course! Well, I spent a lovely few days in Trier and drove the Mosel from Koblenz (and cruised parts of it) into Luxembourg and found it to be really beautiful and complimentary to the Rhine. Even though the terraces are much steeper and more beautiful and the river is narrower, there is the problem that almost all the castles are ruins (c'mon Louis XIV) as fewer were reconstructed and can "stand as evidence" of Romanticism in the way that such a thing happened with the Rhine (which I don't know that UNESCO values so much anyway :), other than Cochem. The Rhine has a spattering of ruins, reconstructions, and even a couple truly preserved castles. I think getting Burg Eltz as a component would be key, as it is really truly one of the best "castle experiences" one can have.

Chad is out of the list, Micronesia and Antigua-Barbuda one up.
