Several countries have expressed interest in OLPC. Here are their basic requirements for writing systems and [[languages]]:

* India -- 10 official writing systems, 20 official languages
* China -- [[Simplified Chinese]], [[Mongolian]] ([[Cyrillic]], Mongolian), [[Tibetan]], and others
* Egypt -- [[Arabic]]
* Nigeria -- [[Hausa]] (Arabic), [[Igbo]] (Extended Latin), [[Yoruba]] (Extended Latin)
* Brazil -- [[Portuguese]]
* Argentina -- [[Spanish]]
* Thailand -- [[Thai]]

In every one of these countries there are dozens to hundreds of minority languages.
