Foreign Policy: Embassy Air Quality Reports From Beijing, Shanghai Jerk Chinese Gov.'s Chain [View all]

Last year, the U.S. Embassy in Beijing caused a sensation when word spread that it was publicly reporting the air quality in Beijing. Chinese micro-bloggers cited an hourly Embassy tweet that often sharply diverged from official government monitoring. Official Beijing city reports generally showed healthful air in the capital; the Embassy meanwhile sometimes called the Beijing air crazy bad. After much criticism, the city vowed to use the same evaluation method as the embassy, reflecting the presence of especially dangerous particulates in the air.
Now, U.S. diplomats are at it again. On Saturday, the U.S. consulate in Shanghai launched a separate hourly Twitter feed of the air there. James Areddy of the Wall Street Journal notes that the initial readings were not reassuring: Unhealthy, unhealthy, unhealthy. The official Shanghai government reading -- good air.
The griping has already begun. The Shanghai Daily quotes Shu Jiong, an environmental professor at East China Normal University, who questioned whether it was proper for the Consulate to use the U.S. standard to evaluate Shanghai's air quality. Shu told the papers reporter: "The two countries have different demographic situations and are at different steps of development, so it will be more suitable to use the Chinese standard to evaluate the air quality in Shanghai."
This is no mere sniping. Pollution has been behind a surge in public discontent over the last couple of years, which is an unacceptable red line for Chinese authorities, who fear social instability and the threat it could pose to their political power. It is a principal reason why China is set on curbing coal consumption, and introducing green technologies into the economy. The timing of the rollout of the Shanghai feed is likely to be met with greater than usual suspicion from some Chinese authorities. Already, this is an exceptional year for Chinese political turbulence, much of it linked to the U.S.
