Rights groups welcome release of Chinese women activists

Rights groups have welcomed China's release of five activists who were held for more than a month, saying it was driven by an international outcry.

The women, who had planned protests against sexual harassment, were detained shortly before International Women's Day on 8 March.

The US, UK and European Union had all called for their release.

The five have not been charged but their bail conditions mean charges could be brought at a later date.

Their lawyer, Liang Xiaojun, said they would need to regularly update the authorities on their whereabouts.

Human Rights Watch's Maya Wang said on Twitter that their release "shows international pressure works on China, when it is strong enough", and that the authorities should "cease harassment".

Amnesty International's William Nee said in a statement that the release was "an encouraging breakthrough", but that "the authorities must now follow through and drop all charges and restrictions against the women".

Lu Jun, the co-founder of Chinese campaign group Yirenping - which some of the women were involved with - said their detention was "a glaring injustice", but that advocacy for the release has "actually furthered legal protection of women's rights and strengthened the rule of law in China".

This year's International Women's Day coincided with China's annual parliamentary session, which usually has tight security and is often preceded by the detention of activists.

The women had planned activities including a march in a Beijing park where participants would wear stickers advocating safe sex, and gatherings in Beijing and Guangzhou calling for awareness of sexual harassment on buses.

China said on Monday it had lodged a formal complaint to the US over a statement by Secretary of State John Kerry at the weekend in which he called for their unconditional release.
