Sources in China's Sichuan province told the Tibetan exile media that a Tibetan monk in Ngaba county (Chinese: Aba) was sentenced to four and a half years in prison on charges of promoting efforts to "split the nation." The sentence was reportedly handed down against Shal-ngo Hortsang Tamdrin on Oct. 29, after he led a public prayer in Zamthang town for Tibetans who have self-immolated, and allegedly called for uniting "the traditional provinces of Tibet." Ngaba county is part of the traditional Tibetan region of Amdo, which is not recognized as an administrative entity by Chinese authorities. The public prayer reportedly took place in April at the Tsangpa Monastery, which was subsequently placed under heavy surveillance by a large contingent of security forces. The number of Tibetans who have self-immolated now stands at 122, with 104 fatalities, according to a count by exile organizations. (Tibet Post, Nov. 21)

New violence is reported from China's far western province of Xinjiang Nov. 16, when a group of Uighur youths attacked the police station in Siriqbuya (Chinese: Selibuya) township, Maralbeshi (Bachu) county, Kashgar prefecture. Two auxiliary officers were bludgeoned to death, and all nine of the attackers were reported to be killed. The youths were said to be armed with knives, swords and sickles The same town was also the scene of deadly clashes in April. Radio Free Asia, citing eyewitness accounts (presumably via cellphone), reported that "residents pleaded with the police not to kill the young Uyghurs"—implying at least some of the deaths may have been extrajudicial executions carried out after the attackers were pinned down or subdued.

Ethnic Uighurs from around the world gathered in Washington DC this week to commemorate the anniversary of two short-lived independent republics set up by their forefathers within what is today the Xinjiang Uighur Autonomous Region of China. Around 100 Uighurs attended a ceremony Nov. 12 at Capitol Hill to remember the establishment of the East Turkestan republics on Nov. 12 in 1933 and 1944. Rebiya Kadeer, president of the Munich-based World Uyghur Congress, praised  those who founded the republics, and called on the Uighur people to remain strong in the face of what she called a policy of "repression" under the current Chinese government. "The Uyghur people have been suffering under the oppressive government of China since the destruction of the Uyghur republics; however, the level of repression has since been extended to our beliefs and customs," she said at the ceremony at the Rayburn House of Representatives Office Building. 

A series of explosions outside the provincial Communist Party headquarters in Taiyuan, capital of China's Shanxi province, left one dead and at least eight wounded Nov. 6. National broadcaster CCTV said more than 20 vehicles were damaged. Coverage inevitably invokes last week's Tiananmen Square attack, which has been blamed on Uighur militants. But South China Morning Post notes that the blasts come a week after "a team of graft investigators from Beijing arrived in Taiyuan to conduct an in-depth review of the province's finances." Authorities have appealed to citizens with personal grievances not to overwhelm the team. There have been several bomb blasts in China over the past years apparently motivated by frustration with official corruption rather than any ideological or ethnic agenda. Shanxi has seen violence in recent years over labor unrest and land disputes.

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.
