Tevez today saw a proposed move to Corinthians fall through, with City claiming the Brazilian club had failed to provide the required bank guarantees on the €44 million (Dh232m) fee.
Joorabchian denied that guarantees were the issue, claiming there were still sticking points over other aspects of the deal, but said that Tevez would remain calm while he waits for his future to be resolved.
The collapse of the Corinthians deal once again makes it a strong possibility that Tevez is forced to remain with City, due to a shortage of suitors who can afford his transfer fee and wages.
But Joorabchian said that, while his client was keen to move, he would not cause his current club problems.
"I think Carlos is a very calm person," Joorabchian told Sky Sports News. "He's neither disappointed nor happy. He's very calm. We waited to see how the deal would be structured and he tried to keep out of it in terms of insisting on anything.
"Now he'll go on holiday after the Copa America and see what happens.
"There was a concrete offer on the table, and it was very close to being negotiated and agreed, but unfortunately it didn't go through. There's not really any speculation from our standpoint [on what happens next].
"He's still a City player and he will respect that. We will keep it like that until there's something else concrete on the table."
Since Corinthians announced in the early hours of the morning that the deal was off, City have indicated it was due to the lack of a bank guarantee, with concerns over how the Brazilian club would fund a deal worth four times their previous transfer record.
Joorabchian dismissed that notion, claiming Fifa rules provided enough security for City.
"It had nothing to do with proof of funds," he said. "They are both Fifa clubs, both Fifa members, and it would be almost impossible for Corinthians not to pay.
"They are the largest club in Brazil. There would not be any issue with it. It is almost like Barcelona, Real Madrid or Manchester United not paying. They are the largest club in South America and with that kind of revenue, I don't think that would be an issue.
"I do know from speaking to Corinthians that City did ask for a bank guarantee and Corinthians said that would be not be a problem if City would want it.
"But from Corinthians' point of view, there was no point in doing so until the offer was agreed, and what kind of offer did they want to agree?"
With the Brazilian transfer window closing early tomorrow, Joorabchian said the deal was now dead without hope of resurrection, but he believes a move could still materialise for Tevez this summer.
"I do think they were very close, and if there were three or four days left in the market, it would have been completed.
"City clearly have an intention of selling Carlos, but now it is going to be a little more complicated.
"It's all speculation at the moment. The market has only been open for two weeks. There are six weeks left. Anything might happen yet."
City appear keen to sign Tevez's Argentina teammate Sergio Aguero regardless of the collapse of the deal, but Joorabchian struck down a suggestion that another ambitious signing would make Tevez change his mind about staying with City.
"Carlos' future has got nothing to do with other players," he said. "He is an individual who bases himself around his own happiness and I don't think it will be anything to do with anyone joining that changes Carlos' mind."
One striker definitely leaving City is Brazilian Jo who is joining Internacional in his homeland.
The 24-year-old was briefly City's record signing when he joined from CSKA Moscow in 2008 for a fee of around £18m, although he was swiftly overtaken in that regard by his countryman Robinho later the same summer.
However, despite the high expectations, Jo never adapted to life in the Premier League, and scored only six goals in 41 appearances for City.
Jo, capped three times by Brazil, also had spells on loan at Everton and Galatasaray, but could not recapture the form that had made him such an exciting prospect in Russia.
