I believe some of these countries have other sources of wheat.
I don't think a certain country will only depend on one supplier of their staple food.
So I am not really worried about this issue because there will be other suppliers around the globe.
Who knows, they will find cheaper alternatives because of this shortage?
There will always be contingencies that will be put in place here.
And besides, Ukraine is not really the very top producer of wheat, China is.
Most of us have a preference for the grain that we consume. Here in India, people in Northern and Western states prefer wheat and corn, while those in the South and East prefer rice and finger millet. Now their food habits won't change all of a sudden, even if there is a large increase in prices. And regarding China, although they produce a huge quantity of wheat, there is still a shortfall. In order to cover this shortfall, they need to import wheat from other countries such as Russia, Australia and Ukraine.
