Chinese authorities have detained an activist for "inciting subversion" after she led a campaign pushing for government officials to publicly disclose their wealth.
A lawyer for Liu Ping says police in the southern province of Jiangxi detained the 48-year-old activist last month. There has not been any public statement on the subversion charges, an accusation often made against government critics.
Separately, Beijing police have reportedly detained 10 other anti-corruption activists. A lawyer for some of those detained told the French news agency police charged the activists with "unlawful assembly" after they displayed a banner calling for greater government transparency.
Rights groups say the detentions call into question the stated commitment of China's new leader Xi Jinping to crack down on government corruption.
Since taking power last year in a once-a-decade power transfer, the new Communist government led by Mr. Xi has vowed to address the widespread corruption, warning it could threaten the party's grip on power.
But the government has also cracked down on those who wish to expose corruption. It has also tightly censored online criticism of government corruption that it views as being too sensitive.
