On June 13, Vice Minister of Foreign Affairs Cui Tiankai made the following statement amidst continued controversy over U.S. embassy and consulate air quality monitoring:
Beijing is over 16,000 square kilometers big. Relying on just one or two points to monitor air quality won’t work. Relying on amateur institutions such as foreign embassies is also unacceptable, and moreover exceeds their function. Ultimately, we must depend on the Chinese people’s own efforts.
