MOSCOW - Russia has not prepared any additional sanctions on the West, a government minister said Thursday.

"We ... were not preparing any proposals on any additional measures," Industry and Trade Minister Denis Manturov told reporters.

Russia expects that the joint projects with the West which are being implemented could be continued, he added.

Meanwhile, Economic Development Minister Alexei Ulyukayev said Russia did not rule out filing complaints to the World Trade Organization (WTO) if Western countries step up their sanctions.

"The situation is dynamic, it depends on the partners' behavior. If they show some de-escalation, then we will restrain from the measures. If not, we will speed them up," Itar-Tass news agency quoted him as saying.
