Chinese Foreign Minister Yang Jiechi will go to Iran for talks on Tehran's nuclear dispute, officials said on Monday.
Yang would visit on Tuesday for meetings with senior officials, a Chinese Foreign Ministry spokesman said.
The West accuses Iran of seeking the ability to make nuclear weapons but Tehran says its atomic program is purely for the civilian purpose of generating electricity.
Iranian President Mahmoud Ahmadinejad said last week his country's nuclear program was irreversible, showing continued defiance in the face of possible new UN sanctions.
Britain, France, Germany, the United States, Russia and China are expected to meet on November 19 to assess reports on Iran from EU foreign policy chief Javier Solana and International Atomic Energy Agency head Mohamed ElBaradei.
With a permanent seat on the UN Security Council, China holds the power to pass or veto possible new sanctions on Iran.
Beijing approved two previous UN resolutions on Iran, but Chinese officials also say that they do not favor sanctions and want more negotiation.
