Russia could support a U.N. Security Council motion on Syria if it doesn’t contain ultimatums to Bashar Assad’s government, the Russian Foreign Minister said on Thursday.

Sergey Lavrov said on a trip to Kyrgyzstan that Moscow may vote in favour of a Security Council document backing U.N. envoy Kofi Annan’s peace plan. Mr. Lavrov didn’t specify whether he was referring to a Council resolution or a statement, but warned that the document shouldn’t contain any ultimatums or threats.

“When we consider a document at the Security Council, we shall proceed from the principle of not doing any harm,” he said. “It would be good if we are able to reach a consensus aimed at helping Kofi Annan’s mission and not use ultimatums that would escalate tensions.”

Russia and China have twice used their veto power at the Council to block U.N. resolutions condemning Mr. Assad’s government over its yearlong crackdown on an uprising in which more than 9,000 people have been killed. But Moscow has strongly supported Mr. Annan’s plan and urged Mr. Assad to take the first step to end bloodshed.

“Russia believes that any steps regarding the Syrian problem should be aimed exclusively at supporting Annan’s mission,” Mr. Lavrov said. “It’s very important not to undermine this process with ultimatums or threats. Regrettably, some are willing to do that, and it refers in particular to the ‘Friends of the Syrian People’ meeting.”

Mr. Lavrov that some participants of Sunday’s meeting in Istanbul made statements that discourage the opposition from observing its obligations under Mr. Annan’s plan.

Mr. Assad agreed this week to implement the ceasefire brokered by Mr. Annan from April 10, 2012. The truce is the keystone of a six-point plan put forward by Annan, the joint U.N.-Arab League envoy. It requires government forces to withdraw from towns and cities, followed by a withdrawal by rebel fighters. Then all sides are supposed to hold talks on a political solution.

“While Kofi Annan has insisted on the demilitarization of cities, statements coming from Istanbul have sent a different signal to the opposition,” Mr. Lavrov said on Thursday.

Saudi Arabia and Qatar have backed the idea of arming the opposition against Mr. Assad’s government, but the West remains opposed. Western nations moved instead to create a fund for the rebels at the meeting in Istanbul.
