I think it should be 'Цао Цаонинг'.

"хитой" цао does retun some results, while хитой тсао doesn't.

Uzbek in Latin script seems to use both 'Sao' and pinyin 'Cao' though, so it can cause problems with romanisation...

As far as I know, the Cyrillic Uzbek doesn't have a ц. I, too, would have preferred to write it this way.

And are the results for Uzbek sites?

Of course it does! (Even though it occurs only in Russian loanwords).

It corresponds to Latin combination TS (after vowels; федерация - federatsiya; example in a dictionary: http://multilex.mail.ru/view_di...ct=A160%2CA161 ) or S (in all other positions; цех - sex ^^):

At least some of them.
"Жангу жадал билан шимолий-ғарбга отланган бу бўлинма кенг шуҳрат қозонган ва Цао Ванлининг деҳқонлар қўзғолонига бориб қўшилган."
"Теннисчимиз дастлабки босқичда Фанг Чи Цао (Хитой)ни 6:2, 6:2 ҳисобида мағлубиятга учратган бўлса..."
"Хан давлати буюк Хитой деворидан Жанубий Хитой денгизигача бўлган територияда ... Мамлакат шимоли ва пойтахт районларида қўзғолон раҳбарларидан бири Цао Цао ..."
"Кенгаш ишида Қозоғистон Республикаси мудофаа вазири Даниал Ахметов, Хитой Халқ Республикаси мудофаа вазири генерал-полковник Цао Ганчуань"
I'm pretty sure this is Uzbek.

Okay. I was going off the English wiki:

http://en.wikipedia.org/wiki/Uz...riting_systems

where the ц never appeared.

I don't feel like correcting the English wiki. :)
