WASHINGTON, United States (AP) — Congress voted overwhelmingly Thursday to suspend normal trade relations with Russia and ban the importation of its oil, ratcheting up the US response to Russia’s invasion of Ukraine amid reports of atrocities.

House action came after the Senate approved the two bills with 100-0 votes. The measures now go to President Joe Biden to be signed into law.

Lawmakers overwhelmingly support the substance of the two Bills, but they had languished for weeks in the Senate as lawmakers worked to hammer out the final details.

Biden has already taken executive action to ban Russian oil, liquefied natural gas and coal to the United States. The legislation puts the effort into law.

The Bill to end normal trade relations with Russia paves the way for Biden to enact higher tariffs on various imports, such as certain steel and aluminum products, further weakening the Russian economy under President Vladimir Putin. It also ensures Belarus receives less favourable tariff treatment.

Rep Richard Neal, D-Mass, said innocent Ukrainians were being slaughtered even as lawmakers were meeting.

“We have no time to waste and must immediately further punish Vladimir Putin,” Neal said. “What we have witnessed in Bucha over the course of the last 72 hours alone more than justifies the positions we have taken in the past and to be more assertive and aggressive going into the future.”

Senate Majority Leader Chuck Schumer, D-NY, announced late Wednesday a breakthrough in negotiations to bring the Bills up for votes before lawmakers travel back to their home states and congressional districts for two weeks. Some lawmakers said that the failure to take final action on the Bills was sending the wrong message to allies and to Russia.

“Now, I wish this could have happened sooner, but after weeks of talks with the other side, it’s important that we have found a path forward,” Schumer said.

Schumer said the images coming out of Ukraine as the war drags on “are pure, pure evil. Hundreds of civilians murdered in cold blood.”

“No nation whose military is committing war crimes deserves free trade status with the United States,” Schumer said moments before the vote.

While there was overwhelming support for suspending preferential trade treatment for Russia, Senator Rand Paul, R-Ky, blocked speedy consideration of the bill over concerns that its language on who can be sanctioned for human rights abuses is too broad, leaving it ripe for abuse. A few other Republicans had voiced similar concerns.

Schumer opted to let senators work behind the scenes on language that lawmakers from both parties and the White House could accept, rather than chew up floor time to overcome the filibuster.

Senator Ben Cardin, D-Md, said, practically speaking, the impact of the delay on the trade bill is minimal “because there’s virtually no trade right now coming in from Russia.” Still, he said passage of the bill is important.

“Messaging is important here and showing action is important,” Cardin said. “You’ve got the Ukrainians on the battlefield every day. The least we can do is get these bills passed.”

The Bill also provides the president with the authority to return normal tariff treatment for Russia as well as resume trade in Russian energy products subject to certain conditions.

While Russian oil makes up only a small part of US imports, it carries a high price for lawmakers in Congress who viewed the ban as a moral test in blocking an economic lifeline for Putin’s regime.

The White House says that sanctions the US and more than 30 other nations have already enacted have stung the Russian economy. It said that experts are now predicting Russia’s GDP will contract up to 15 per cent this year and that inflation is already spiking above 15 per cent. More than 600 private sectors companies have already left the market.

“Russia will very likely lose its status as a major economy, and it will continue a long descent into economic, financial, and technological isolation,” the White House report said.
