The British government has threatened to freeze Russian oligarchs’ property in the U.K. if Russia invades Ukraine. Is the threat credible?

The threat undermines “Ukraine’s position on international markets” said the Atlantic Council’s Peter Dickinson. “Companies can’t finance themselves.”

More than one-third of Europe’s natural gas supplies come from Russia.

Russia supplies much of Europe’s natural gas through pipelines in Ukraine. But energy diversification may reduce Russia’s leverage.

Russia relies on technology imported from the rest of the world, especially the U.S., Europe, Korea and Japan.

To avert war in Europe, we may have to absorb “political, economic and diplomatic costs,” said Eddie Fishman of the Atlantic Council.

As Russian troops accumulate at the Ukrainian border, some fear the country could withhold natural gas to Europe in the event of military conflict.

Why U.S. counterintelligence officials are telling companies to be wary about foreign business deals.

The U.S is threatening further sanctions against the Nord Stream 2 natural gas pipeline linking Russia and Germany.

The route, which saves more than 10 days of travel, is a test case for a Russian energy company that wants to ship gas to China through the summer.
