It is not always possible to access annual reports and financial statements on the websites of public companies from emerging markets. Try the following service as an alternative:

ISI Emerging Markets
Contains pdf annual reports and/or standardized downloadable financial statement data for listed companies from 60 emerging markets including Brazil, Russia, India and China. Select the country of interest, then the Company tab and Listed companies only (there is also information on some private companies, but not financial data).

ISI Emerging Markets is available from Library > E-Resources > By alphabetical order.  It is currently available on campus only.
