Meanwhile, Poland's foreign ministry says it's in the process of extending shelter, work permits, and education to Ukrainian refugees. CGTN's Lu Sirui has more details.

LUKASZ JASINA Polish Foreign Ministry Spokesperson "Two million people reached Poland since the beginning of Russia's aggression to Ukraine. Many of our Ukrainian guests left Poland to Germany to France to Canada, United States. But still we've got much more than a million of them among us.

Thanks to our efforts, nobody's hunger, everybody lives in the warm and good facilities. And today starts a very important action of registering them into the polish national ID named Pestle. Polish state organized for them right to work and leave, many of them already started to work in Poland. There's even a first new Ukrainian restaurant on the streets of Warsaw organized by the people like them.

But there are difficulties as you say, first are schools. Education system is in crisis after pandemic, like many educational systems in Europe and in the world. The Ukrainian children are coming to school already and thanks to the heroic efforts of our teachers."

LU SIRUI CGTN Reporter "So how big of an impact is the refugee exodus having on Poland society and its economy?"

LUKASZ JASINA Polish Foreign Ministry Spokesperson "The cost would be growing and that is why Poland is waiting very impatiently for the funds for recovery from the European Union and a four promised help from a European Union, United States and others, because not everything could be based on our own structure, and the pockets of our people. The biggest impact is that they are coming towards the biggest city.

They are in small cities in eastern Poland, where people didn't see multicultural society since the end of the second world, because almost every polish person now talks about Ukrainians who educate, helped Ukrainian, minority, hopefully, is afraid of the migrants."

LU SIRUI CGTN Reporter "So hope for the best and prepare for the worst. As you said, it's just like yeah, it's just the first two weeks, so do you have any plans should the situation continues to get worse before it gets better."

LUKASZ JASINA Polish Foreign Ministry Spokesperson "We can never have a perfect plan for everything. But we will wait to see how many people are coming. The first is immigrants. And of course, still a big danger of the Russian rockets, bombs dropping very closely polish border, for example, in the city of Lviv. We think about this, but we hope that it would never happen, because any kind of attack on Polish soil, and that's a declaration of the American, Germans, British. And that's a very big danger not only for us, for people, but also for the peace in the world."
