BRUSSELS, Dec 15 - President Volodymyr Zelensky urged European Union leaders on Wednesday to swiftly impose new sanctions on Russia before it invades his country and warned that acting after any conflict would be far too late, The Associated Press reported.

Speaking to reporters in Brussels, Zelensky said Ukraine stands ready to enter into talks with Russia to ease tensions, but that Russian President Vladimir Putin does not so far appear willing to come to the table.

The EU’s 27 national leaders will weigh how best to prevent a Russian invasion at a summit on Thursday. A statement drafted for their meeting, seen by The Associated Press, warns that “any further military aggression against Ukraine will have massive consequences and severe cost in response.”

“For us, it is important to have sanctions applied before, rather than after, the conflict would happen, because if they were applied after the conflict would happen, this would basically make them meaningless,” Zelensky said.

“We have war going on for eight years. We understand that only if the sanctions are applied prior to the armed conflict would they become a prevention mechanism for any possible escalation,” he said.

U.S. intelligence officials say Russia has moved 70,000 troops toward Ukraine’s border and is preparing for a possible invasion early next year. Moscow denies that it has any plans to attack Ukraine, but did so in 2014 when it annexed the Crimean Peninsula.

Zelenskyy said he and some EU leaders discussed five options for responding to any Russian attack, but he provided no details. European officials argue that it's a better deterrent to keep Putin in the dark about what measures might be used against him.

Earlier, European Commission President Ursula von der Leyen said the EU has a battery of fresh sanctions ready if Moscow sends its troops across the border. Beyond scaling up existing sanctions, she said, the EU can adopt “unprecedented measures with serious consequences for Russia.″

Asked by reporters whether Europe would act on Zelensky’s call, EU Council President Charles Michel said: “We have sanctions in place, we are ready to take additional sanctions if needed, and we will see” what happens.

The U.S. and the EU have been coordinating their response to the Russian, but no real details of any sanctions have emerged. EU nations are divided between those in the east that think sanctions should be imposed immediately, and others like France and Germany who fear that could provoke an invasion. (ap/ez)
