The story of Al-Jazeera English correspondent Melissa Chan's expulsion from China has a disturbing coda.
New York, May 17, 2012--A journalist who criticized Bahrain's proposed union with Saudi Arabia was seized from his home near Manama on Wednesday and his whereabouts are unknown. The Committee to Protect Journalists called today for his immediate release.
Pity those of us who monitor the ups and downs of China's popular microblog platform, Sina Weibo. For every story its users spread in defiance of local censorship, there follows a clampdown. Whether it's the latest strike against rumors, or real name registration, or newly banned keywords, there's always another restriction in the works as the service struggles to keep a lid on sensitive conversations without driving away its user base. "China tightens grip on social media," we might report, as the Financial Times did in April. And last October. (The U.K.-based newspaper also noted China's grip tightening on lawyers in March.) It's not that these headlines are misleading. They simply show how difficult it is to illustrate the grip that always tightens, but never quite suffocates.
New York, May 3, 2012--Chinese security officials' ongoing obstruction of foreign and domestic journalists covering dissident Chen Guangcheng is a worrying sign for supporters trying to secure his safety, the Committee to Protect Journalists said today. Authorities in Chen's native Shandong province have kept the blind, self-taught lawyer isolated from the media since September 2010.
The battle over blind Chinese activist Chen Guangcheng's freedom and well-being is a battle over information. Both Chinese and U.S. officials are trying to spin the story their way. A few activists and media claim to speak for Chen, and in China's anti-press environment they are putting themselves at risk. Direct interviews with the man himself are hard to come by.

As the Internet and mobile communications become more integrated into reporters' work, the digital threats to journalists' work and safety have increased as well. While many press reports have documented Internet surveillance and censorship--and the efforts to combat them--mobile communications are the new frontline for journalist security.
New York, May 1, 2012--Syrian security forces harassed a credentialed camera crew from the British broadcaster Sky News as the team was filming an impromptu demonstration in Damascus today, according to news reports. Authorities briefly confiscated a camera and detained two journalists, the reports said.
News of blind legal activist Chen Guangcheng has been censored for months. International news reports of his escape last week from incarceration in his home in Linyi, Shandong--apparently to U.S. protection, although his whereabouts remain unclear--has only intensified that censorship. That is unlikely to stop discussion among those familiar with Chen's case.
New York, April 26, 2012--A court in Hunan province has sentenced local resident Hu Lianyou to two years in prison for defaming a police chief in online writings, according to local news reports.
New York, April 13, 2012--Chinese authorities should halt their censorship of Web content in the aftermath of senior politician Bo Xilai's dismissal, the Committee to Protect Journalists said today. Internet officials in China have deleted at least 210,000 online posts and shut down as many as 42 websites since mid-March for allegedly spreading rumors, the state-run news agency Xinhua reported on Thursday.
