On the question of the overall impact, I think there's no question that the fallout from the war and its economic and social impacts have been enormous. It has been on Ukraine. The humanitarian situation in Ukraine remains extremely difficult. Bombs can come at you anywhere in the country at any time. It's clear that Russians have been targeting civilian infrastructure and civilian sites. They've killed thousands and thousands of innocent people who are not involved in the conflict.
It's had a traumatic impact on Ukraine, but it's also had a strong economic and social impact on the rest of the world, because Ukraine, as you pointed out, is a major supplier of food and fertilizer. The ports in Ukraine have been widely used, through the Black Sea, to get food products throughout the world. Those supply lines were disrupted. A number of the ports, including Mariupol, were completely and utterly destroyed. Russians have continued to bomb in Odessa, despite the fact that there's a deal now to get the grain out. The impacts have been extraordinary, as I said, on the people of Ukraine and globally.
Globally, naturally, I have to say there was a perception expressed by a number of countries that the west is responding this way to Ukraine and Ukrainian refugees, to the humanitarian needs with the amount of aid that we're supplying, but when it came to their situation they don't see the same level of response. That's been an ongoing challenge for us, as one of those countries that has been so supportive of Ukraine, to say that we can actually be supportive of more than one group at a time.
I think Canada's immigration policies and our refugee policies have helped us in terms of our own credibility as a country in saying, “Here's what we're doing across the board.” We have, subject to what happens this afternoon at four o'clock, maintained a very high level of support and assistance to a number of countries. We have maintained our emergency assistance. We've maintained and increased our support for the humanitarian agencies, for OCHA, not only in the work that it does in Ukraine, but throughout the world. Our overall share of the UN budget remains very high. We're among the top-10 donors to the United Nations and all of its agencies. We're keeping a strong position in talking to African countries, Asian countries and others that are recipients of large amounts of food products and other things from the region. We're saying that we're doing what we can to help.
I don't think anyone should underestimate the impact of the food inflation, the impact of the cost of inputs into agriculture and the overall impact this is having on developing countries. It's had a serious impact on their financial, economic and social situations. I don't think we should underestimate it.
