A moratorium on attacks on ships in the Black Sea is being prepared between Russia and Ukraine. Turkey has resumed trade with the Black Sea region, leading to a slight increase in the grain market. Wheat and corn prices in Paris and Chicago have risen due to slow exports from Russia and potential damage to the US crop. Both countries have agreed to cease attacks on each other's energy infrastructure for 30 days, and are also working on a moratorium on strikes on naval and cargo ships carrying grain in the Black Sea. The negotiations for this moratorium will be held in Turkey.
