"We believe that the new proposed Russian mechanism does not have the standards for investigation and attribution that were included in the earlier UN Security Council versions that would have extended the JIM [Joint Investigative Mechanism] mandate back in November," Nauert said.
On Tuesday, Russia introduced a draft UN Security Council resolution to create a new international investigative body to objectively probe the use of chemical weapons in Syria. Chinese Ambassador to the United Nations Liu Jieyi told members of the UN Security Council same day that China welcomed the draft resolution.
UK Deputy Permanent Representative Jonathan Allen said later that the United Kingdom was studying the Russian draft resolution.
