WASHINGTON - US President Barack Obama called Russian President-elect Vladimir Putin on Friday to congratulate him on his election victory and the two discussed issues including Iran, Syria and missile defense, according to a White House statement.

Obama made "reset" of US relations with Russia one of his top foreign policy priorities after taking office three years ago. He had a solid working relationship with departing Russian President Dmitry Medvedev.

"President Obama and President-elect Putin agreed that the successful reset in relations should be built upon during the coming years," the White House statement said.

While listing Iran and Russia's invitation to join the World Trade Organization as areas of cooperation, the statement said the two leaders agreed to continue discussions on areas where their countries have differed, including Syria and missile defense.

Putin served as president for eight years until 2008 and has been prime minister during Medvedev's four-year presidential tenure.
