Russia and Ukraine have reached a agreement, brokered by Turkey and the UN, to reopen Ukrainian ports on the Black Sea and allow the transport of grain to the rest of the world. The agreement includes the release of Russian exports of grains and fertilizers. The blockade imposed by Russia on the operation of Ukraine's ports has sent food prices soaring around the world and led to grain shortages. The main importers of Ukrainian grain are developing countries such as Egypt, Indonesia, Bangladesh, Turkey and Yemen. The war will also lead to a reduction of the Ukrainian crop, with about 30% not being harvested.
