Any Russian response to fresh sanctions from the U.S. is unlikely to cause any major harm for American investors and could merely be a symbolic gesture, according to one political analyst.

Moscow stepped up its war of words against Washington Wednesday after the U.S. House of Representatives voted overwhelmingly in favor of imposing new sanctions. A prominent member of the upper house of Russia’s parliament said that the country should consider a “painful” response for the U.S.

“Judging by the unanimous vote in the U.S. House of Representatives on the sanctions package against Russia, Iran and North Korea, there will be no breakthrough (in U.S. and Russia relations) … In fact, further degradation of bilateral cooperation is becoming inevitable,” Konstantin Kosachyov, chairman of the Russian Foreign Relations Committee and member of the ruling United Russia party, said on his Facebook page on Wednesday.

The planned sanctions on Russia were initiated to further punish the country for its annexation of Crimea in 2014 and alleged role in the destabilization of eastern Ukraine. The bill, which passed by 419 votes to three, proposes new restrictions on oil and gas projects.

Russia’s Foreign Minister Sergei Ryabkov also said Wednesday that it had repeatedly warned Washington that it was growing tired of showing restraint and would be prepared to retaliate in the event of any hostile moves towards Moscow, the Interfax news agency reported.

Ryabkov argued the proposed sanctions would leave no room for ties between the two countries to improve in the near future, before adding the vote had taken the relationship into uncharted waters.

Meanwhile, prominent Russian Senator, Franz Klintsevich told the RIA news agency that future cooperation between Moscow and Washington in fighting terrorism would be complicated if the drafted bill is signed by President Donald Trump.

Analysts at Eurasia Group predicted that the U.S. legislation codifying and modestly expanding sanctions on Moscow would most likely prompt a “more symbolic than substantive” response.

“Russia is not likely to take new action against U.S. investors in the country – though there’s a low but worrisome chance that (President Vladimir) Putin will feel compelled to target at least one large U.S. corporate as a show of strength,” Eurasia Group analysts said in a research note Tuesday.

The White House said in a statement that it would review the bill amid speculation President Trump could attempt to veto it. The bill now needs to be passed through the Senate before it can be signed by the president.

“While the president supports tough sanctions on North Korea, Iran and Russia, the White House is reviewing the House legislation and awaits a final legislative package for the president’s desk,” Sarah Sanders, White House spokeswoman, said Tuesday.

The U.S. already has an array of sanctions in place against both Russian companies and individuals. In December, amid allegations of election hacking, then-President Barack Obama closed two Russian compounds and expelled 35 Russian diplomats.
