Three new ships were authorized yesterday to take part in a deal allowing the safe Black Sea export of Ukraine grain.

Global wheat prices fell further a day after Russia agreed to extend the pact for 60 more days.

Russia had threatened to quit the Black Sea agreement if a list of demands to overcome obstacles to its own grain and fertilizer exports was not met by yesterday.

The Kremlin says it extended the agreement because some results from talks had given it certain hopes, but more progress needed to be made.

The U.N. and Turkey brokered the deal for an initial 120 days last July to help tackle a global food crisis that has been aggravated by Moscow’s invasion of Ukraine, one of the world’s leading grain exporters.

The deal had ground to a halt on Wednesday after the last authorized ship left a Ukrainian port.
