This essentially says that Han were in general barred from the Privy Council, which is not at all exciting news since that was the highest governing apparatus of the Yuan Dynasty, along with the Central Secretariat and the Censorate. Of course these positions would be staffed mostly (but not even exclusively) by Mongols. What YOU said is that Han were "barred from holding power", which is of course patently false since pretty much every political institution save the top echelons were held mostly or even exclusively by Han Chinese, and even the top echelons had some Han officials, as your own link acknowledges.
I agree with you on this one. To add a few examples to your point that Han is not barred in high positions. I would say that in Yuan, the ethnity of individual did not play any role in promoting, if it ever played any role at all.
However, you are confusing me with your stands, I will explain at the end after the examples.
[example]
1.
, a Khitan, was the imperial Chancellor of Yuan dynasty during Kublai's rein. That is a position only under the Emperor himself. High enough in your view?
He is a Han in Yuan's caste system. Han is the third caste out of four, low enough in your view? Now you can make your own judgement, is Han barred from the highest governing apparatus? My judgement is, NO.
2.
, a Han, was another Chancellor of Yuan, predecessor of Yelu Chucai.
3.
, a Han, brought up by Shi Tianze, was a general who served for Yuan. He was involved in the defeat of Song dynasty to the south. He commanded the artillery corps of the Mongols that broke the wall of Baghdad in 1258 under the command of Hulagu. If you call Hulagu as the field marshal, then Guo Kan is a full general. (a note to the wiki page though, Guo Kan was instrumental in the sacking of Baghdad, but whether he became the governor of Baghdad afterwards were not clear as I have not come across Yuan's official records to prove it.).

Han as a caste class, (later on became the foundation of Han ethnic definition), is first officially recognized by Yuan dynasty (in 1300s). That is pretty late, isn't it?
was a Sinicized Khitan, a proto Mongol people. You can see that from his name. But he is put into Han. That means Han was a mix, a big mix. Included in Han were all people in Northern China who were not Mongol tribes under the Khan (Emperors) direct command up till the time of Yuan's establishment, that includes the proto-Han, Khitan (Mongolic, ex Liao Dynasty), Jurchen (Manchu's ancestor, ex Jin Dynasty) and some other Mongols who fought against the Borjigin leadership.
The fourth caste was "southerners", including any people of ex Song Dynasty and Dali Kingdom in the south. These include proto Han and Yue (related to Vietnamese) and Dai (related to Thai) etc. in south west China.

All the examples above tell one thing and one thing only, that is in China, Race/Nation/Ethnity has no role in being a member of the empire, the state, the country and the citizen.
So I am very confused by you.
On the one hand you seem to say (in my impression) that Han and non-Hans are distinct, separate, should be separated (by referendum or self determination or whatever western BS). The evidence is your rejection of plawolf's comparison between Londonner/British and Tibetan(or Mongols for that mater)/Chinese.
On the other hand, you seem to subscribe to the idea that China is and should be kept in one piece regardless ethnity proven by your view of Yuan's inclusive policy.
Which one is really your stand?
