Obama Vows New Bid To Thwart Iran Nuclear Effort

President Barack Obama says sanctions on Iran are having "enormous bite," but he still wants to work with Russia and China to find more ways of putting pressure on Tehran to halt its nuclear program.

At a news conference Sunday after the APEC summit in Hawaii, Obama didn't specify those measures -- and said he's still not taking any options off the table.

At the summit, Obama met with Russian and Chinese leaders to discuss a new report from the U.N. watchdog agency that included evidence Iran's program is working on research and design efforts to develop a nuclear bomb.

Obama said Russia and China share America's goal of making sure Iran doesn't build the bomb. But both countries have said they oppose new sanctions.
