The Oct. 28 deadly incident in Tiananmen Square—in which an SUV ploughed into the crowd, leaving five dead and nearly 40 injured—appears to have been an act of terrorism. Police are reportedly checking hotels and vehicles for two men said to be ethnic Uighurs. It is unclear if the two suspects survived the crash or are thought to be accomplices. Accounts also do not make clear if the car's occupants were all killed in the crash; Reuters called the incident a "suicide attack," but also implied the attackers set the SUV on fire after driving it into the tourist-packed square. The Uighur ethnicity of the suspects has not been officially confirmed, but is based on surnames provided in police notes left with hotel management in the city to assist in the dragnet. Radio Free Asia cites reports from locals that police are checking ID cards of Uighurs on Beijing's streets and instructed hotels not to accept patrons from Xinjiang.

An in-depth Sept. 29 Reuters report on the multi-billion-dollar but very murky jade trade in Burma raises the specter of "blood jade"—without actually using the phrase. Almost half of all jade exports are "unofficial"—apparently spirited over the border into China with little or no formal taxation, representing billions of dollars in lost revenues. Official statistics are said to indicate that Burma produced more than 43 million kilograms of jade in fiscal year 2011-12, worth a low-balled $4.3 billion. Yet official exports of jade that year stood at only $34 million. (It isn't explained how all that "unofficial" jade made it into the production stats in the first place.) China doesn't publicly report how much jade it imports from Burma, but jade is included in official imports of precious stones and metals, which in 2012 were worth $293 million—a figure too small to account for billions of dollars in Burmese jade.

Security forces in China's far western Xinjiang region last month shot and killed at least 12 men and wounded 20 others during a raid on what authorities described as a "terrorist facility," Radio Free Asia reported Sept. 17. Local officials told Radio Free Asia that the men had been building and testing explosives at a desert encampment near Jigdejay village, Poskam county (Chinese: Zepu), outside the city of Kashgar. One resident said the police were tipped off to the presence of the encampment after a rocket launcher the men were trying to build accidentally exploded, killing one of them.  

Over 100 ethnic Tibetans were injured and one man committed suicide in Yulshul (Chinese: Yushu) prefecture* in the Kham region of Eastern Tibet (officially in Qinghai province), as Chinese military forces broke up protests against diamond mining in the area Aug. 19. As in similar protests elsewhere in Qinghai earlier that week, protestors put up large banners printed with President Xi Jinping's recent speech on environmental protection, and charged that the mines have not been approved by China's central government. The clash apparently began when some 1,000 protesters occupied two traditional Tibetan sacred sites, identified as Atod Yultso and Zachen Yultso, at a mine in Dzatoe (Chinese: Zaduo) township, and security forces fired tear-gas to disperse them. Eight protesters were detained, but two identified as leaders are reported to have "disappeared."

Ethnic Tibetans protesting what they called illegal mining operations clashed with Chinese security forces in Gedrong Zatoe county, Qinghai province, Aug. 16. Exiled Tibetan activists with contacts in the region told Phayul news service that the protesters have pledged to block the mining operations, citing the threat to local watersheds. Hundreds of troops arrived at the three townships  where protesters were mobilzing, and issued an "ultimatum" to call off the campaign or face arrest. Local Tibetan leader Khentsa Soedor reportedly said, "You can kill us but we will not let the mining take place here. It is our responsibility to protect our environment which is a source of water to many other countries." Authorities detained Soedor's wife for interrogation, and his whereabouts are now unknown.

Chinese writer, lawyer and human rights advocate Yang Maodong, commonly known by his pen-name Guo Feixiong (HRIC profile), on Aug. 17 became the second leader of the New Citizens movement to be arrested on suspicion of disrupting the peace. This follows the detainment of fellow New Citizens leader Xu Zhiyong  in July, in what appears to be a targeted crackdown on the human rights movement. Yang's family noted a recent lack of communication starting earlier this month, but were unable to confirm he was missing until his sister received a message from the Tianhe branch of the Guangzhou police in southern China on Saturday that he was detained nearly two weeks ago. These arrests are thought to be connected to publication of Xu's latest article, calling for a political revolution, as well as protests against newspaper censorship led by Yang. The two leaders are deeply involved in several rights campaigns, including Chinese Human Rights Defenders  and Pen International.

The Supreme Court of the Philippines on July 23 issued a "temporary environment protection order" against 94 "small-scale mines" that extract nickel in Zambales, Central Luzon region. Activists who brought the petition claim that among the "small" mines are at least five fronts for giant nickel miners from China. The mines are operating under small-scale mining permits (SSMPs) that can be granted by provincial authorities in special minahang bayan, or People's Mining Areas, under a new policy instated by the Benigno Aquino administration. But local peasants charge that the mines are operating outside the designated areas, and go essentially unregulated, causing grave pollution to local waters. The Chinese parent companies, said to really be a single coordinated venture, are identified as Jiangxi Rare Earth & Metals Tungsten Group, Wei-Wei Group, and Nihao Mineral Resources Inc. They set up the five "small mines" through Filipino dummy companies, bribing officials to look the other way. The SSMP policy, enacted by executive order last year, has sparked a new mineral rush in the Philippines. (Philippine Star, July 24; Inquirer Mindanao, July 15, 2012) 

Chinese activist and lawyer Xu Zhiyong was arrested by authorities July 17 on suspicion of having "gathered crowds to disrupt public order." Xu, a law lecturer at the Beijing University of Posts and Telecommunications and founder of the Open Constitution Initiative (Gongmeng), was placed under house arrest on April 12. Xu's arrest came after President Xi Jinping pledged to increase efforts to combat government corruption. Xu was previously detained by Chinese police in 2009 on charges of tax evasion. Coinciding with Xu's arrest, earlier this week Wang Wenzhi, a reporter for the official Xinhua News Agency, accused China Resources (Holdings) chairman Song Lin of corruption. The article was later removed.
