Title:
2008_Sichuan_earthquake

Context:
On May 15, 2008 Geoffery York of the Globeandmail.com reported that the shoddily constructed buildings are commonly called "tofu buildings" because builders cut corners by replacing steel rods with thin iron wires for concrete re-inforcement; using inferior grade cement, if any at all; and using fewer bricks than they should. One local was quoted in the article as saying that "the supervising agencies did not check to see if it met the national standards."

Question:
Who was supposed to inspect building to see if they met national standards?

supervising agencies
