The Chinese Embassy in Mexico has a fairly detailed page on visa types and fees, separated by passport type. I'm not sure if you're guaranteed to receive one if you apply as a foreigner, but that's as best as you can get from the officials.

Check the web page of the EMBAJADA DE LA REPUBLICA POPULAR CHINA EN LOS ESTADOS UNIDOS MEXICANOS because they have different types of visa, separated by number of entries or exits, and for nationalities that request the visa. But the average price is about from 1890 MXN to 2180 MXN (about 90 to 103 USD).
