China's Foreign Ministry joined Russia Thursday in warning Western countries that additional pressure on Iran would not solve the nuclear stand-off.
Beijing reacted to a new report by the International Atomic Energy Agency (IAEA) which said this week that there are many concrete indications that Iran worked towards developing a nuclear weapon.
Several Western powers including France have raised the possibility of new sanctions, should Iran not start answering the IAEA's questions on this topic.
"We, as always, believe that dialogue and cooperation are the only effective approaches for properly resolving the Iran nuclear issue," Chinese Foreign Ministry spokesman Hong Lei said.
"Imposing pressure and sanctions cannot fundamentally resolve the issue," he added.
The last round of talks between Iran and the grouping of the United States, Britain, France, Germany, Russia and China ended without result in January.
A senior Western official said Thursday in Vienna that diplomatic efforts were underway to show a united front among these six powers at a meeting of the IAEA governing board next week.
