The Black Sea maritime security deal aims to bring Moscow back to predictable grain and fertiliser markets that would allow for profit and ensure global food security, Russian Foreign Minister Sergei Lavrov said in remarks published late on Tuesday.

The United States reached separate deals on Tuesday with Ukraine and Russia to cease fighting in the Black Sea and pause attacks against energy targets, with Washington agreeing to push to lift some sanctions against Moscow.

"We want the grain and fertilizer market to be predictable, so that no one tries to 'ward us off' from it," Lavrov told the Russian state Channel One television.

"Not only because we want ... to make a legitimate profit in fair competition, but also because we are concerned about the food security situation in Africa and other countries of the Global South."
