The World Food Programme (WFP) said it was optimistic about a U.N.-brokered deal to reopen Ukrainian ports for grain exports but warned the agreement alone will not solve the global food crisis even if it is implemented effectively.
Russia, Ukraine, the United Nations and Turkey signed a deal on Friday aimed at allowing safe passage for ships going in and out of three Ukrainian Black Sea ports that have been blocked by Russia since Moscow's Feb. 24 invasion.
