The Blues will take on the Ligue 1 outfit at Parc des Princes for the first leg of the quarter-finals next Wednesday.
While Mourinho has claimed that PSG are favourites to progress into the semi-finals at the expense of Chelsea, Blanc is refusing to get into a war of words with his counterpart.
"I will not play this game," Blanc said in a press conference. "It is my choice. Mourinho is going to talk, to comment, it's the way he operates."
The second leg will take place at Stamford Bridge on April 8.
