China holds that all parties concerned should refrain from taking any action that may lead to the escalation of the situation on Iran nuclear issue, Chinese Forein Ministry spokesman Liu Jianchao said Tuesday.

Liu said some new situation emerged in Iran nuclear issue and China will continue to consult with other members of UN Security Council on relevant issues.

Iran confirmed to have launched a second cascade of centrifuges last Sunday and vowed to conduct peaceful utilization of nuclear energy.

The United States and other western countries are calling for a draft UN resolution that would impose sanctions on Iran.
