The English Wikipedia and MathWorld don't mention it either.
Do these Chinese mathematicians (Cao and Zhu) really make a critical
contribution to the Conjecture?

If, as the article states, "Cao and Zhu put the finishing touches to
the complete proof of the Poincaré Conjecture, which had puzzled
mathematicians around the world, said Professor Shing-Tung Yau, a
mathematician at Harvard University" -- then it is most likely true.
Shing-Tung Yau is an eminent differential geometer who won the Fields
Medal in 1982. He also seems to be the first internationally
renowned mathematician who has been willing to assert that the
Poincaré Conjecture has been proved.
