AMMAN: Jordanian Islamists on Sunday called on Muslims and Arabs to boycott Russian and Chinese products after the two countries vetoed a UN Security Council resolution condemning Syria's regime over bloodshed.

"By vetoing the resolution, Russia and China have shown that they are taking part in the killing of Syrian people," Hammam Said, the leader of the powerful Muslim Brotherhood, said on the group's website.

"All Muslims and Arabs should boycott Russian and Chinese products in order to support the Syrian people, who demand freedom and dignity. The vetoes were against all Arabs and Muslims."

Said described the crackdown, which rights groups say has killed more than 6,000 people since democracy protests broke out in March last year, as "almost the worst in recent history."

Russia and China on Saturday used their diplomatic muscle for the second time in four months to block a resolution condemning the violence.

The other 13 countries in the 15-member council voted for the resolution, proposed by European and Arab nations to give strong backing to an Arab League plan to end the crackdown.
