U.S. President Joe Biden delivered a major address in Poland on Saturday, rallying support for Ukraine and calling for unity in the face of Russian aggression.
Ukraine's President Volodymyr Zelenskyy has urged energy-producing countries to increase their energy output, so "everyone in Russia understands that no one can use energy as blackmail."
It comes as countries across Europe and beyond seek to reduce their energy dependency on Russia — a major oil and gas producer and exporter.
Russians may be trying to encircle Ukrainian forces in east
Russian forces appear to be trying to encircle Ukrainian troops who are facing separatist fighters in the far east of the country, according to a new intelligence assessment.
The U.K. Ministry of Defence, in its daily update, said on Sunday that Russian units are trying to advance southward from Kharkiv and northward from Mariupol. If successful, those maneuvers could cut off Ukraine's soldiers who are already engaged against separatists in Donetsk and Luhansk.
CNBC was unable to independently confirm the ministry's report.
Kharkiv and Mariupol are both still in Ukrainian hands but have been blasted for weeks by Russian artillery, killing civilians and defenders alike. Ukraine's government this week refused a Russian demand that it surrender Mariupol.
Russia claims that it isn't using artillery against civilian targets, despite overwhelming evidence that it is.
Meanwhile, tenacious Ukrainian defensive efforts continue to block Moscow's invasion in the north of the country, which would include the long-stalled Russian drive toward Kyiv.
"The battlefield across northern Ukraine remains largely static with local Ukrainian counterattacks hampering Russian attempts to reorganise their forces," the British ministry said.

Biden to Poland: "Your freedom is ours"
U.S. President Joe Biden has told Poland's President Andrzej Duda that "your freedom is ours," echoing of one of Poland's unofficial mottos. He assured Duda that the U.S. and other NATO allies would come to their aid if Russia should attack.
The two gathered Saturday on Biden's final day in Europe to speak about their shared effort to end the war in neighboring Ukraine.
Biden called the "collective defense" agreement of the Western military alliance a "sacred commitment," and said that the unity of NATO was of the utmost importance. He also acknowledged that Poland was bearing the brunt of the humanitarian crisis, with more than 2 million of the 3.5 million people fleeing Ukraine entering the country. He said the other NATO allies must do more. The U.S. has pledged to accept up to 100,000 refugees.
Duda said that the relations between the two nations are flourishing, despite the difficult times.

Biden says Putin was counting on being able to divide NATO, calls on more countries to accept Ukrainian refugees
President Biden in a meeting with Polish President Andrzej Duda stressed the importance of unity among NATO nations during the Russia-Ukraine crisis.
"I'm confident that Vladimir Putin was counting on being able to divide NATO," Biden said, and "to be able to separate the eastern flank from the west, to be able to separate nations based on past histories. But he hasn't been able to do it."
Biden went on to say that NATO countries should follow Poland's lead in accepting Ukrainian refugees, including the U.S. He compared the refugee crisis to the situation at the southern border in the U.S.
"And also we do acknowledge that Poland is taking on a significant responsibility, that I don't think should just be Poland's; it should be all of NATO's responsibility. The fact that so many, so many Ukrainians seeking refuge in the country of Poland. We understand that because we have at our southern border thousands of people a day, literally not figuratively, trying to get into the United States. But we believe, that we, the United States, should do our part relative to Ukraine as well by opening our borders to another 100,000 people," Biden said.

TotalEnergies will not do more business with Putin, but will maintain Russian assets
Patrick Pouyanne, chairman and CEO of TotalEnergies, says the company will never do business with President Vladimir Putin again.
Still, Pouyanne said TotalEnergies won't write off its oil and gas assets in Russia. Instead it will no longer provide capital for new projects in the country and not renew its Russian gasoil and crude supply contracts.
Speaking to CNBC's Hadley Gamble, Patrick Pouyanne, chairman and CEO of TotalEnergies, said he was not prepared to write off the company's assets in Russia as it would effectively mean giving them to Putin "for free."
"What do we do with the existing assets? ... I am not ready to give them for zero to Russian people, to Russian oligarchs … because by the way, it would be contrary of the sanctions," he said on a CNBC-moderated panel at the Doha Forum in Qatar.
"These assets are there, I will not give them for free to Mr. Putin. Because this is what it means, leaving today."

Ukraine war is pushing countries toward a 'parallel system' of pricing oil, Qatar says
Qatar's Foreign Minister Mohammed bin Abdulrahman Al-Thani tells CNBC that the economic effects of the Ukraine-Russia crisis are being felt around the world — and could lead some countries to move away from pricing oil in dollars.
"Honestly speaking, look at what happens and the dynamics around us right now. I'm sure there are a lot of other countries who are unhappy with what's happened and the consequences of the Ukrainian-Russian crisis, especially the economic consequences," he told CNBC's Hadley Gamble at the Doha Forum.
"And they are going to look and explore a parallel system [of pricing oil] … going to hedge, at least, for them economically," he added. "So as we are living through a transition, this transition will not be only a political transition but it is an economic transition as well."
He added that Qatar was "stepping up" and holding talks with European countries about boosting gas supplies.
It comes as European countries seek to diversify their energy supply away from Russia – particularly gas. The EU imported 45% of its gas from Russia last year, according to the International Energy Agency.
"We are stepping up and helping some European partners who are starting to suffer from some gas shortages … with the limited amount that we have," he said, stressing that the majority of its gas contracts are long-term.

Ukraine's Zelenskyy to energy producers: I ask you to increase output
Ukraine's President Volodymyr Zelenskyy has spoken at the Doha Forum conference's opening ceremony, urging energy producing countries such as Qatar to hike their output.
Speaking via video link, he said: "I ask you to increase output of energy so everyone in Russia understands that no one can use energy as blackmail," according to a translation.
It comes as countries around the world seek to reduce their energy dependence on Russia — a leading producer and global exporter of oil and gas.
Posting on his verified Telegram channel after the address, Zelenskyy said it was only a matter of time before European countries stopped purchasing Russian oil and gas.
"The responsible states, in particular the State of Qatar, are reliable and reputable suppliers of energy resources. And they can contribute to stabilizing the situation in Europe. There is much that can be done to restore justice," he said, according to a translation.
On Friday, the U.S. said it will look to provide at least 15 billion cubic meters more of liquified natural gas to Europe this year, with the volumes expected to increase going forward.
U.S. President Joe Biden described the agreement as a "groundbreaking" new initiative designed to "increase energy security, economic security and national security."
U.K. Ministry of Defence says Russians likely to concentrate firepower on urban areas
The U.K. Ministry of Defence said Russia seems likely to focus its artillery on urban areas.
"Russian forces are proving reluctant to engage in large scale urban infantry operations, rather preferring to rely on the indiscriminate use of air and artillery bombardments in an attempt to demoralise defending forces," the ministry said in its daily intelligence update.
It said, however, this strategy will likely come "at the cost of further civilian casualties" as Moscow looks to "limit its own already considerable losses."
The ministry said Russia's onslaught continues in a number of Ukrainian cities, including Kharkiv, Chernihiv and Mariupol.

Pentagon official says Russian forces focusing more on Donbas, less on Kyiv
Russian forces appear to be prioritizing efforts in Donbas in eastern Ukraine, a U.S. Department of Defense official said Friday.
"That's where still there remains a lot of heavy fighting and we think they are trying to not only secure some sort of more substantial gains there as a potential negotiating tactic at the table, but also to cut off Ukrainian forces in the eastern part of the country," the official said.
While airstrikes on Kyiv continue, the Pentagon official said Russian forces currently do not appear to be pursuing a ground offensive in Ukraine's capital city.
The official also said the Pentagon has seen Russian troop movements in Georgia, which they said could indicate reinforcements may be sent into Ukraine.
Reports of military movements in Ukraine continue to be difficult to confirm as the situation across the country remains fluid and changes rapidly.
The official also confirmed Ukrainian forces destroyed a Russian ship in Berdyansk earlier in the week, but declined to say what weapons were used, in order to protect operational security. The official also said the department does not know how many Russians were onboard when the ship was hit or how many casualties there were.

We're in a fight between democracy and oligarchs, Biden tells U.S. troops in Poland
U.S. President Joe Biden stopped near Rzeszow, Poland to thank the U.S. Army 82nd Airborne Division ahead of his meeting with the country's President Andrzej Duda in Warsaw.
"We're in the midst of a fight between democracy and oligarchs," Biden said.
"What's at stake here is not just what we're doing in Ukraine to try to help the Ukrainian people and try to keep the massacre from continuing," Biden said. "Beyond that is what are your kids and grandkids going to look like in terms of their freedom."
"What you're engaging in is much bigger than whether or not you can alleviate the pain and suffering of the people of Ukraine. We're in a new phase, we're at an inflection point," he said. Biden added that the world will not be the same in 10 or 15 years and the question is: "Who's going to prevail," democracy or autocracy.
"You are the finest fighting force in the history of the world," Biden said.
In addressing the troops, Biden invoked his son Beau Biden, a lawyer and officer in the Army Judge Advocate General's Corps who served in Iraq and Kosovo.
"There are hundreds of thousands of people like my son, like all of you. So thank you, thank you, thank you, thank you," Biden said.
