"This is an important sign that Beijing wants to nip the New Citizens movement in the bud," Xiao Shu said. "In the past, the authorities were ambivalent toward civil society, but now how they are treating Wang will send a clear signal that they consider the New Citizens movement as a hostile force that should be suppressed."
In a sign of public attention to the case, Wang became the third most-searched person behind two entertainment celebrities on China's Twitter-like Sina Weibo on Friday despite temporary efforts to block searches of his name.
Guo Yushan, a Beijing scholar, also said Wang has been targeted for his association with Xu. "In essence, this is political suppression," Guo said. "It is consistent with the political style of the new administration."
Wang has openly protested Xu's detention and vowed to help move the New Citizens movement forward.
He also posted online video footage a lawyer took of Xu, in which the civil rights campaigner delivered a bold message from behind the bars, urging citizens to unite in pursuing democratic freedoms.
Wang is among a growing group of Chinese businesspeople who have been pushing for gradual social changes in China. Wang has been an advocate for building a civil society and always identifies himself as a "citizen." He has lobbied for equal rights for students and urged more public involvement in social events.
"His speech is very mild, but his stance is firm, and that gives him power," Guo said.
