President Joe Biden met with the prime ministers of Australia, India and Japan on Thursday where the Quad leaders discussed the conflict in Ukraine.

"The Quad leaders discussed the ongoing conflict and humanitarian crisis in Ukraine and assessed its broader implications. They agreed to stand up a new humanitarian assistance and disaster relief mechanism which will enable the Quad to meet future humanitarian challenges in the Indo-Pacific and provide a channel for communication as they each address and respond to the crisis in Ukraine," the White House said in a statement.

French President Emmanuel Macron tweeted about his meeting with Russian President Vladimir Putin, saying, "At this point, he refuses to cease his attacks on Ukraine. Maintaining the dialogue to avoid human tragedies is absolutely necessary. I will continue my efforts and contacts. We must avoid the worst."

He added, "A dialogue to protect populations, to obtain moves that will avoid human tragedies, to put an end to this war: this is the meaning of my commitment alongside President Zelensky and the international community. My determination is and will remain total."

Canada announced a new program on Thursday that will "cut through red tape" to expedite arrivals for Ukrainians seeking temporary or permanent residency, said Sean Fraser, Canada's minister of immigration, refugees and citizenship.

"There is no limit on how many can apply," Fraser said.

"All those who arrive in Canada as part of these measures will be eligible for open work permits and will quickly be able to work if they so choose," Fraser noted.

He went on, "Our commitment to Ukrainians goes beyond the historic ties between Canada and Ukraine and beyond the cultural connections between our people. It's a commitment to humanity."

The sanctions will expand upon recently announced EU sanctions, block specific oligarchs’ travel to the U.S. and target the oligarchs’ relatives, according to the official.

While Poland has been welcoming refugees fleeing the destruction in Ukraine, the country will eventually meet its limit on how many people it can take in, Konrad Fijolek, president of Rzeszow, Poland, a city about 60 miles from the Ukrainian border, told ABC News.

Like many cities that border Ukraine, Rzeszow, a town of about 180,000 people, has become a pathway to safety and a lifeline for millions of refugees flooding across the border from Ukraine.

Poland will be able to receive about 1.5 million people, but any more will put the country under strain, Fijolek said.

"If a million or more come, we won't be able to cope," he said.

Some estimates suggest as many as 4 million people could leave Ukraine due to the conflict, but most of the major cities in the country are already full — and officials are attempting to move refugees into smaller cities, a feat that is "not easy," Fijolek said.

So far, all the shelters set up in Poland are temporary, he added.

"We would like to avoid the view of refugee camps here," he said. "We would like people who are escaping from the war to think that what awaits here is proper camp not camps."

In addition, the mental state among the people in Poland is continuing to deteriorate, Fijolek said.

"We as local leaders would like to send the message that if there's any possible action to stop the war [find it] and then try to negotiate, because every day at the border we can see the human tragedy," he said.
