Why isn't there more attention to this in the international press?
Simple IMHO like many parts of the world there is little constant coverage of such places as Peru, look at the campaigning over Darfur, or the lack of attention to the famine in Ethiopia or Somalia until newsreel film shocked a few, Western audiences.

Many press agencies have reduced their overseas presence and others rely on locally taken footage (not voices) before committing their own resources.

I understand that other parts of the international press watch the world differently, such as Spain in Latin America and France with some it's former colonies. How does Japan now report on Peru?

Reporting aside it is too easy to label countries such as Peru as disasters and what will change? Look at the thread on Zimbabwe as an example.
