Everyone is very concerned about the issue of the Strait of Hormuz because the strait is an important oil transit channel, Wen said at a press conference during his official visit to Qatar.

"Any extreme acts across the Strait of Hormuz, under whatever circumstances they are taken, are against the common interests and aspiration of the people across the world," Wen said.

Cargo transportation through the strait should be protected because it in the interests of the?entire humanity, Wen added.

China is not the only country which has oil trade with Iran, Wen said. China's "normal" and "justified" trade with Iran should be protected.

Normal trade should be protected, otherwise, the normal international order would be disturbed, Wen continued.

"I am not worried about the the normal trade between China and Iran at all," Wen said.

China maintains that the Iranian nuclear issue should be resolved through peaceful means, he said, adding that China's stance will not change.

Beijing supports the political process between Iran and the Iran Six, a diplomatic group made up of the United States, China, Russia, Britain, France and Germany.

China firmly opposes Iran producing and possessing nuclear weapons and will work with concerned parties to establish a nuclear-free Middle East, Wen said, while stressing that China will not trade its principles for profits.

Wen arrived in Doha on Wednesday morning after his visit to the United Arab Emirates.
