The Asian Football Confederation website, online sport news quoted Troussier as saying in the Chinese daily Sports Weekly that both countries have expressed an interest in signing the well-travelled French coach.
Having taken Japan to the second round of the World Cup last year, Troussier was rumoured to be at the top of China's wish list, but he has now been approached by two of the Middle East's most ambitious footballing nations.
"The Qatar FA have officially invited me for the post but I will need some time to think over it," said the former Nigeria and South Africa coach.
"I told them that I will give them an affirmative answer by June 15. Personally, I am very interested in the job.
"That being said, I will still need time to think this through," he continued.
He said:"The chances of me taking on the Qatar job are 50-50 and I will really need to consider my options. I have also received an official invitation to coach Iran and I will need to consider the various options being tabled."
Troussier was reportedly in Doha over the weekend and, like Frank Leboeuf and Steffan Effenberg, who have both recently signed for Qatari clubs, the Frenchman was just as impressed with the set-up in the country.
"Qatar are positioned nicely to improve very quickly over the next few years. Conditions are great and the FA are very enthusiastic about the development of football in the country.
"For me, the immense trust that they've given me is a great encouragement. From youth development to picking the players, I have been promised to be given full responsibility and their ambition to improve is very admirable.
"If I don't have the confidence to lead Qatar, I would not have even considered their invitation," added the Frenchman.
He added:"There is a lot of potential in the country, but in comparison to countries like Japan and China, Qatar will need to work a lot harder to bridge that gap."
