Washington/Moscow: The United States on Thursday imposed a broad array of sanctions on Russia, including curbs to its sovereign debt market, to punish it for interfering in last year’s US election, cyber hacking, bullying Ukraine and other alleged malign actions.

The US government blacklisted Russian companies, expelled Russian diplomats and barred US banks from buying sovereign bonds from Russia’s central bank, national wealth fund and Finance Ministry. The United States warned Russia that more penalties were possible but said it did not want to escalate.

The Russian Foreign Ministry reacted angrily, summoning the US ambassador for a diplomatic dressing-down to tell him “a series of retaliatory measures will follow soon.” A ministry spokeswoman also said a possible summit could be imperilled.

Russia denies meddling in US elections, orchestrating a cyber hack that used US tech company SolarWinds Corp to penetrate US government networks and using a nerve agent to poison Kremlin critic Alexei Navalny.

US President Joe Biden spoke on Tuesday to Russian President Vladimir Putin to raise concerns about those issues and the buildup of Russian forces in Crimea and along the border with Ukraine, although a top US general saw only a “low-to-medium” risk of a Russian invasion in the next few weeks.

Biden, who also proposed a US-Russian summit, is trying to strike a balance between deterring what Washington sees as hostile Russian behaviour, while avoiding a deeper deterioration in US-Russian ties and preserving some room for cooperation.

“My bottom line is this: There is an interest in the United States to work with Russia. We should and we will,” Biden said in remarks to the press.But “when Russia seeks to violate the interests of the United States, we will respond,” he said. “I was clear with President Putin that we could have gone further, but I chose not to do so. I chose to be proportionate.”

Russia said Washington’s actions contradicted a stated US desire to normalise relations with Moscow. The sanctions are hostile steps that heighten the countries’ confrontation, a Russian Foreign Ministry spokeswoman said.

Among his moves, Biden signed an executive order authorising the US government to impose sanctions on any area of the Russian economy and used it to restrict Russia’s ability to issue sovereign debt to punish Moscow for interfering in the 2020 US election.

Biden barred US financial institutions from taking part in the primary market for rouble-denominated Russian sovereign bonds from June 14. US banks have been barred from taking part in the primary market for non-rouble sovereign bonds since 2019.

He did not prohibit them, however, from buying such debt in the secondary market, a step likely to have a far more dramatic effect on the Russian bond and currency markets, which fell as news of the sanctions seeped out before recovering some losses.

The Treasury also blacklisted 32 entities and individuals that it said had carried out Russian government-directed attempts to influence the 2020 presidential election and other “acts of disinformation and interference.”

In concert with the European Union, Britain, Australia and Canada, the Treasury also put sanctions on eight individuals associated with Moscow‘s occupation of Crimea, which Russia annexed from Ukraine in 2014.

The White House said it was expelling 10 Russian diplomats in Washington, including representatives of the Russian intelligence services, and for the first time, formally named the Russian Foreign Intelligence Service (SVR) as the perpetrator of the SolarWinds hack. The agency said the allegations were “nonsense” and “windbaggery.”

The US government plans a new executive order to strengthen its cybersecurity, a US official told reporters, suggesting it could include such elements as encryption and multifactor authentication.

The White House also said it would respond to reports Russia had offered bounties to Taliban-linked militants to kill US soldiers in Afghanistan. US intelligence agencies have “low-to-moderate” confidence in their assessment of those reports, in part because they rely on sometimes undependable testimony from detainees, it said.

Russia has long brushed off allegations of putting bounties on US soldiers in Afghanistan.Andrew Weiss, a Carnegie Endowment for International Peace think tank analyst, was skeptical the US sanctions would change a “largely competitive and adversarial relationship” in the short term or deter Russia in the long term.

“I’d be surprised if today’s very calibrated announcements by the Biden administration materially shift the relationship in either direction,” he said, saying Russia was willing to cooperate on some issues but there was unlikely ever to be a meeting of the minds on Ukraine or election interference. 

“I don’t think it’s realistic to expect the new sanctions will shift Russia’s risk calculus in a fundamental fashion,” he added. “It’s to be expected that the Russians will keep probing and testing our resolve.”
