As a veto member of the UN security council, China will simply prevent any response. In addition, they pay massive amounts of money to African countries to vote their way. Look into Ethiopian-Chinese relations and the Ethiopian cholera outbreaks and you'll see why the WHO leader (not a doctor I'd add) did nothing but shill for China.

Btw, things still aren't all clear in Rwanda and from what I hear things are starting to go south again, including Paul Rusesabagina (the main character from the movie) accusing the Rwandan government of kidnapping him and forcing him into a rigged trial[0]. Speaking to a Rwandan friend all he could say is that things were certainty shady and things aren't going well in the country right now. Remembering one of the most powerful lines of the movie

> You're black. You're not even a nier. You're an African.

What people criticize about the Rwandan genocide isn’t the lack of military intervention. It is the lack of any response from the international community (think the first decade of HIV/AIDS). No condemnation, no UN response, no relief of asylums for victims, and hardly any news.

On 11 January 1994, General Roméo Dallaire, commander of UNAMIR, sent his "Genocide Fax" to UN Headquarters.[108] The fax stated that Dallaire was in contact with "a top level trainer in the cadre of Interhamwe-armed [sic] militia of MRND." The informant—now known to be Mathieu Ngirumpatse's chauffeur, Kassim Turatsinze,[109] a.k.a. "Jean-Pierre"—claimed to have been ordered to register all Tutsi in Kigali. According to the memo, Turatsinze suspected that a genocide against the Tutsis was being planned, and he said that "in 20 minutes his personnel could kill up to 1000 Tutsis".[110] Dallaire's request to protect the informant and his family and to raid the weapons caches he revealed was denied.[110]
