BEIJING (Reuters) — A senior Chinese official demanded on Tuesday that foreign embassies stop issuing air pollution readings, saying it was against the law and diplomatic conventions, in pointed criticism of a closely watched U.S. embassy index.
The level of air pollution in China’s heaving capital varies, depending on the wind, but a cocktail of smokestack emissions, vehicle exhaust, dust and aerosols often blankets the city in a pungent, beige shroud for days on end.
Many residents dismiss the common official readings of “slight” pollution in Beijing as grossly under-stated. The U.S. embassy has installed a monitoring point on its roof which releases hourly air-quality data via a widely followed Twitter feed.
The U.S. consulate in Shanghai provides a similar service.
While China tightened air pollution monitoring standards in January, the official reading and the U.S. embassy reading can often be far apart.
Chinese experts have criticized the single U.S. embassy monitoring point as “unscientific”.
Deputy Environment Minister Wu Xiaoqing went a step further, saying such readings were illegal and should stop, though he did not directly name the United States.
“According to the Vienna Convention on Diplomatic Relations… foreign diplomats are required to respect and follow local laws and cannot interfere in internal affairs,” Wu told a news conference.
