Russian President Dmitry Medvedev has said he could run for a second term in 2012 but made clear a job swap with his powerful Prime Minister Vladimir Putin was also possible.
The issue of who will take the Kremlin post in 2012 is a sensitive one for investors in Russia drafting their mid-term plans.
"If I work well, if people trust me, why not run?" Mr Medvedev, in Pittsburgh for a summit of the G20 group of leading economies, told a student during a question-and-answer session at Pittsburgh University.
Mr Medvedev was elected president last year with the strong support of his predecessor and mentor Vladimir Putin.
Mr Putin remains more popular and influential than Mr Medvedev, however, and some Russia-watchers speculate Putin is planning to return to the presidency in 2012.
He fuelled a wave of speculation earlier this month by telling foreign academics and journalists he and Medvedev would decide which of them will run in the next elections.
Mr Putin said he and Mr Medvedev would not compete.
Economic crisis has not damaged the two men's popularity ratings and either would be favourite to win the next presidential poll if he ran.
In Pittsburgh, Mr Medvedev moved to soften the impression given by the prime minster's remarks.
"This does not mean we are deciding for others, this only means that we politicians should hold consultations," he said.
"I am ready to work in a different job as long as it is useful for the country," he said, after being asked whether he was prepared to swap jobs with Mr Putin in 2012.
