March 24, 2022 Russia-Ukraine news

US President Joe Biden says he hopes to see Ukrainian refugees when he visits Poland on Friday, though he said he doubted witnessing the crisis first-hand would alter his approach.

Biden is expected to visit Poland on Friday, where millions of refugees have fled amid the war in Ukraine. Precise details of his visit there are being closely held for security reasons.

Biden, noting he’d visited “many, many war zones,” said he understood the plight of migrants. 

“I've been in refugee camps. I've been in war zones for the last 15 years. And it's -- it's devastating,” he said. “The thing you look at the most is you see these young children that are in those camps.”

Biden said visiting with refugees would reinforce his view that the US must act in a major way to assist in the relocation of those displaced by war.

“The United States is the leader of — one of the leaders in the international community. Has an obligation to be engaged,” he said.

More context: At least 10 million people have been forced to flee their homes in Ukraine following Russia's invasion less than a month ago, the head of the United Nations' refugee agency said Sunday.

Of those who have left their homes, the majority — 6.48 million as of March 16, according to figures provided by the International Organization for Migration on Friday — have been internally displaced since the conflict began on Feb 24.

Others have sought refuge in neighboring countries, including Poland, Romania, Moldova, Hungary, Slovakia, Russia and Belarus.

More than 3.2 million people have fled Ukraine since the Russian invasion in late February, according to the United Nations High Commissioner for Refugees.

The Polish Ministry of the Interior said Friday that at least two million refugees fleeing the war in Ukraine have crossed the border into Poland. The number of refugees still in Poland is considerably lower, with many of those fleeing the conflict continuing their journey to other European countries.

US President Joe Biden said leaders discussed the possibilities of food shortages triggered by the Russian invasion of Ukraine.

Biden said food shortages will be "real," and he called Ukraine and Russia the "breadbasket" for Europe.

Supplies from the two countries together account for almost 30% of global wheat trade.

"We had a long discussion in the G7 with ... both the United States, which has a significant — the third largest producer of wheat in the world — as well as Canada, which is also a major, major producer. And we both talked about how we could increase and disseminate more rapidly food ... In addition to that, we talked about urging all the European countries and everyone else to end trade restrictions on sending, limitations on sending food abroad. So we are in the process of working out with our European friends what it would be, what it would take to help alleviate the concerns relative to food shortages," he said.

Biden also mentioned a "significant" US investment model for humanitarian assistance, which would include food.

Separately, French President Emmanuel Macron laid out the details of a proposed EU-led food security initiative designed to alleviate the risk of food shortages caused by the war.

“This situation will create a food crisis, extremely serious humanitarian situations in several countries and are sure to have massive political consequences in several countries,” Macron said at a news conference in Brussels on Thursday.

According to a document circulated by the Elysée, Russia is the top exporter of wheat worldwide (33 million tons in 2021) with Ukraine not far behind (fourth largest exporter, with 20 million tons in 2021).

The document estimates 27 mostly African and Middle Eastern countries source over 50% of their wheat from Russia or Ukraine.

The three-pronged initiative spelled out in the document would rely on measures, such as making crisis stockpiles of grain available to “avoid any shortages and keep prices down,” raising production thresholds, and stepping up investments in sustainable agriculture in the most-affected countries.

US President Joe Biden said he believes China understands the potentially dire economic consequences that would ensue should the country provide assistance to Russia in its war in Ukraine.

Biden said he had a “very straightforward conversation” with Chinese President Xi Jinping last week on the topic.

He said he “made no threats,” but did make clear that Xi “understood the consequences of him helping Russia.”

He said he pointed out the consequences of Russia’s behavior, and pointed out that China had sought to develop stronger economic ties with the West. He said he told Xi “he'd be putting himself at significant jeopardy in those aims, if, in fact, he were to move forward.”

“I think that China understands that its economic future is much more closely tied to the west than it is to Russia. And so I am hopeful that he does not get engaged,” Biden said.

US President Joe Biden said Russian President Vladimir Putin had indicated to him in their early conversations that he believed the NATO alliance would not remain united.

US President Joe Biden said that the US would respond if Russian President Vladimir Putin used weapons of mass destruction, but that the response would depend on the situation.

"So you've warned about the real threat of chemical weapons being used. Have you gathered specific intelligence that suggests that President Putin is deploying these weapons, moving them into position or considering their use? And would the US or NATO respond with military action if he did use chemical weapons?" the Associated Press asked the US President during his news conference.

Earlier today, NATO Secretary General Jens Stoltenberg said the alliance will reinforce its chemical, biological and nuclear defense systems on fears Russia is planning to use such weapons against the people of Ukraine.

In remarks after meeting with NATO leaders in Brussels, US President Joe Biden said "we're determined to sustain" efforts outlined during the emergency NATO meeting right after Russia's invasion of Ukraine and "to build on them." 

Biden said the US is ready to welcome 100,000 Ukrainian refugees in to the country. The President also confirmed new sanctions on hundreds of Russian individuals and members of government.

"NATO has never, never been more united than it is today. Putin is getting exactly the opposite what he intended to have as a consequence of going into Ukraine," he said.

US President Joe Biden is speaking at a news conference at the NATO headquarters in Brussels, Belgium, after meeting with other world leaders of NATO, the European Council and the G7 as they seek to align their responses to Russia's invasion.

A downed power line tower, burned-out cars and apartment complexes gutted by military strikes can be seen in new video from Mariupol, which was posted by the Ukrainian city's council on Thursday.

CNN has geolocated and verified the authenticity of the video.

The video starts with a car driving south down Krupina Street. This area of western Mariupol has seen intense fighting for weeks, and nearly every single building — including a number of hospitals — in the area has sustained significant damage.

The trees around them are charred, with most of their branches seen splintered around them on the ground.

The apartment complexes on the left are also charred. On a side road between two of the apartment buildings, the bombed-out remains of a city bus and bulldozer are seen. 

A clear blue sky is seen through the apartment building-turned-debris pile, with only portions of the facades and balconies still standing in parts of the building.

Further down the street, the remains of a local gym is seen. 

Any Russian use of chemical or biological weapons in Ukraine “would be a breach of all rules, all agreements and all existing conventions,” German Chancellor Olaf Scholz said after an extraordinary G7 meeting in Brussels on Thursday. “We can only say: Don't do it!”

Scholz firmly rejected Russian allegations that that Ukraine was developing chemical or biological weapons. 

Scholz also rejected Russian President Vladimir Putin’s demand that “unfriendly” countries begin paying for Russian gas in rubles.

“The currency of payment is part of the contract and that is what is valid. Mostly it reads euros or dollar,” Scholz said in Brussels. 

He conceded that energy had been left out of Western sanctions on Russia in response to its invasion of Ukraine, but said that was intentional.

It was a “very conscious decision” of the bloc to exclude the imports of oil, gas and coal from the packet of sanctions. The bloc was working on further sanctions, said Scholz. 

In order to lessen Germany's dependence on Russian energy, the country will begin the construction of two liquefied natural gas terminals to receive natural gas this year, Scholz said.
