Ruiz, who was born in the United States but fights as a Mexican, caused one of boxing's biggest upsets in NY in June when he handed Joshua a first defeat to win the WBA, IBF and WBO title in NY.
He said: "When I regain those belts".
"I will go to the ring well-prepared, to show my heart".
Briton Joshua has been encouraged to take a stand but, while he acknowledged some discomfort, his immediate focus is on reclaiming his WBA, IBF and WBO heavyweight titles.
When asked how he would respond if the bout was used to "sportswash" any improper conduct from the host country, he added: "If that was the case, I would definitely have to say I would be bothered - but my only focus is the boxing".

Ruiz said all the pressure was on Joshua ahead of the rematch. Ruiz, who has only lost once before - to New Zealand's Joseph Parker - said: "There's no way that I'm going to let these belts go. When I jabbed I pushed him away".

"If I make a crap presentation, I could get the fights I've been chasing!"
"I know he's lost weight and will try to box me around, but it's just may job to prevent that".
Joshua, meanwhile, came in at 237 pounds which, according to Dan Rafael , is the lightest he has weighed for a fight since 2014. Joshua, who has played down the significance of the weigh-in all week, said: "Sparring governs your weight.
