BERLIN, (Reuters) – Ursula von der Leyen of the European Commission revealed details on sanctions Russia could face if they invade Ukraine. This included a ban on Russia from accessing major export markets as well as cutting off international financial markets.

So far, Western leaders are not willing to discuss the specifics of what they will do if Russia invades. Instead, they only rule out a military response but promise economic sanctions unprecedented in their scale.

Von der Leyen said that Russia “would in principle be disconnected from the international finance markets.” She spoke to ARD public television on Sunday evening. According to Von der Leyen, sanctions will be placed on all goods Russia makes that Russia needs urgently in order to modernize and diversify its economy.

According to her, sanctions will not be applied until the invasion is complete. This was contrary to calls made by Volodymyr Zelenskiy on Saturday for sanctions immediately.

She stated that Russia’s move towards sanctions was so significant and important, and she believes we should always allow Russia the chance to negotiate and return to diplomacy. “The window of opportunity is still wide open.”

Russia, with some 150,000 soldiers stationed along Ukraine’s borders to the east and north, demands that Ukraine not be permitted to join NATO. Russian President Vladimir Putin believes this is crucial to Russia’s long-term security.

Von der Leyen heads the executive of 27 members in Europe and said Russia’s dependence upon fossil fuel exports is its weakness.

She stated that Russia’s exports account for two-thirds of its total output, while half of Russia’s budget is derived from these countries. Russia had to modernize, which would be impossible if sanctions were increased.
