China, frequently cloaked in yellow haze, told the US Embassy to stop publishing their own reports on air quality in the country, escalating its objections to a popular US Embassy Twitter feed that tracks pollution in smoggy Beijing.

US Embassy officials did not immediately comment, but the Twitter feed was operating nomally.
