CAF president Issa Hayatou announced in his speech in Khartoum:
"On February 12, a proposal was forwarded to the FIFA Executive Committee to include results of CHAN matches in the FIFA rankings."
I doubt FIFA will agree since they don't include CHAN matches in the rankings because CHAN rules restrict the eligibility of players.
However, politics are usually more important than football.
Maybe AFC should take note and ask FIFA to "upgrade" AFC Challenge Cup matches from friendlies to continental qualifiers since the winners advance to the Asian Cup final tournament and most of the teams involved in the Challenge Cup don't participate in the main qualifiers.
