US President Barack Obama has suggested tougher sanctions on Iran over its continuous pursuit of nuclear weapons.

Speaking at the 47-nation nuclear security summit in Washington, Obama urged world leaders to take joint action to prevent terrorist groups from obtaining nuclear weapons, according to Reuters.

Obama said that China had agreed to help negotiate a new UN sanctions resolution on Iran but that Beijing still had economic concerns about sanctions.

During the summit, China sought Security Council resolution to promote a diplomatic way out of the nuclear stand-off as Iran is China's third-largest crude oil supplier.

International Atomic Energy Agency director general Yukiya Amano said that Iran might reduce cooperation with UN inspectors if further sanctions were imposed.
