President Biden signed the $40 billion Ukraine aid bill into law Saturday, the White House announced in a press release.

The bill provides supplemental emergency funds to Federal agencies to respond and provide assistance to Ukraine.

Ukrainian President Volodymyr Zelenskyy thanked Biden on Twitter for the aid.

"The leadership of US, President Biden & the American people in supporting Ukrainians fight against the Russian aggressor is crucial. Look forward to new, powerful defense assistance. Today it is needed more than ever," Zelenskyy said.

The Russian Foreign Ministry on Saturday published a list of American citizens who are barred from entering the Russian Federation on a permanent basis.

Russia said the move was in retaliation for anti-Russian sanctions currently imposed by the U.S.

The list published on the ministry's website comprises 963 U.S. citizens, including President Joe Biden.

More than 40 countries will be represented at the second meeting of the Ukraine Contact Group, formed last month to coordinate international support for Ukraine, according to Pentagon press secretary John Kirby.

Monday's meeting "will allow us to continue to dip into a process to get Ukraine, or at least to make other nations available and knowledgeable about what Ukraine needs as the fight is ongoing," Kirby told reporters during a briefing Friday.

More than 40 nations attended the first meeting both virtually and in-person at Ramstein Air Base in Germany. New countries will attend the second, which will be strictly virtual, Kirby said.

"There are some countries that have shown an interest in participating that weren't in the first meeting," said Kirby, who called the first iteration "a true global community" of countries in NATO and beyond.

Russia's Ministry of Defense claimed Friday it has taken complete control of the Azovstal plant and Mariupol from the Ukrainian forces, expelling them from the port city.

The underground facilities of the plant, in which the Azov National Regiment militia were hiding, came under the complete control of Russian forces, the ministry claimed.

The commander of the Azov Regiment was reportedly taken out of the territory of the plant in an armored car, the ministry said.

Russia claims 2,439 Ukrainian servicemen have laid down their arms and surrendered since May 16.

White House national security advisor Jake Sullivan hinted Thursday of more sanctions coming against Russia in the "next week or two" aimed at targeting ways Moscow is evading sanctions already imposed.

“Where our focus will be over the course of the coming days is on evasion,” Sullivan said Thursday at the Economic Club of Washington. “As Russia tries to adjust to the fact that it’s under this massive economic pressure, what steps do they take to try to evade our sanctions and how do we crack down on that? And I think we'll have some announcements in the next week or two that identify targets that are trying to facilitate that evasion both inside Russia and beyond."

When Sullivan was asked whether sanctions will automatically be lifted if a negotiated peace deal between Russia and Ukraine is worked out, he appeared cautious with his words, saying, “a lot of that depends on what the shape and scope” of the agreement is.

“A lot of it depends on what the Ukrainians, in consultation with us and the Europeans come to agree to," Sullivan said. "You know, we're not going to do a deal over the head of the Ukrainians where we give a bunch of sanctions relief to Russia. But if some measure of sanctions relief were built in to some credible diplomatic solution led by the Ukrainians, that's something that we would happily discuss."

But Sullivan said Russian oligarchs shouldn't expect to ever get back their yachts and other assets seized under sanctions that have been imposed, saying the ultimate goal is "not to give them back” once the war is over.

“The president is actively looking at how we can deal with the fact that as we seize these assets, our goal is not to give them back. Our goal is to put them to a better use than that," Sullivan said. "But I'll be careful in what I say today because there's an ongoing kind of policy process around how we end up dealing with that question. But, rest assured, that the goal is not just to sit on them for a while."
