Let hard numbers speak:
A more complete search indicates that a large fraction of the papers that contribute to the exceptionally high Hirsch factor of EG Wang are papers driven by him, with the rest involving collaborations of various nature (local or international). First, there is absolutely nothing wrong with international collaborations, as scientific research ideally has no boundary. Nowadays, many (if not most) scientists in the west conduct scientific research collaboratively. Let's do not apply double standards here. Second, essentially every recently elected relatively young member of the Chinese Academy of Sciences has done his or her most highly cited papers collaboratively with colleagues in the respective field, be the collaborators inside China or overseas. Perhaps the only easily identifiable exception is K. Lu, who was elected to the CAS several years ago and did most of the high impact papers at his job base Shenyang. Thirdly, the high h factor (h=27 as of today) and the high citations (total over 2500) of EG Wang is phenomenal for scientists inside China, especially in (condensed matter) physics. Again, I found only K. Lu having better such hard indices (h=33, total citations over 4000), whereas the other shining relatively young stars who are EG Wang's peers and who have recently been elected to the CAS have substantially lower h factors and total citations (any one has better statistics about this??? If so please share). In fact, Wang's hard numbers are better than many of the full professors or even chair professors in major research institutions in the west.
It is perfectly imaginable that, given the demanding obligations of EG Wang as the IOP director for 8 years, it is simply unavoidable for him to be in repeated confrontations with some people or interest groups inside and/or outside IOP. Anyone with a fair common sense could tell that the person (or two?) posting attacking messages in the dark here must have been in conflict with EG Wang while working inside the IOP, perhaps because of inability to survive in the highly competitive environment of IOP (guessing here, sorry if it is an incorrect guess)...
