Note:
(a) The high-speed rail between Mexico City and Querétaro, Querétaro
en.wikipedia.org/wiki/Querétaro,_Querétaro
will be 212km. The latter is northwest of Mexico City.
(b) Clement Tan (reporting from Hong Kong), China Rail Stocks Sink After Mexico Shelves High-Speed Rail Line. Bloomberg, Feb 2, 2015 www.bloomberg.com/news/articles/
("On Friday [Jan 30], Mexican President Enrique Pena Nieto said the Yucatan peninsula rail project fell victim to broader budget cuts. The nation, which depends on oil revenue to fund about a third of federal spending, is reducing 2015 outlays by 124.3 billion pesos ($8.3 billion) on expectations oil prices may continue to slump for years")
(i) Last year, Mexico has three high-speed rails in mind: Querétaro line, Yucatán project and a third. Bidding for Yucatán peninsula rail project was expected to start this year, but according to the same Bloomberg report China Railway Construction Corp (CRCC) "was expected to bid on" the Yucatán project.
(ii) So China should take it personally.
(iii) There is no need to read the rest of the Bloomberg report.
I do not know whether Mexico President Enrique Peña Nieto departed Beijing earlier than planned. However, days before CELAC was to be held in Costa Rica, Nieto cancelled without explanation. But everybody could see the reasons: 43 Mexican students were killed and burned.
