KYIV, Aug 31 - The United Nations chief sent Russia a new proposal aimed at getting its grain and fertilizer to global markets in hopes of reviving the deal that allowed Ukraine to ship almost 33,000 tons of grain at a time of growing global hunger.

But Moscow wasn’t satisfied with the letter that U.N. Secretary-General Antonio Guterres sent Russian Foreign Minister Sergey Lavrov earlier this week, The Associated Press reported.
