UNITED NATIONS - UN Secretary-General Antonio Guterres will meet Ukrainian President Volodymyr Zelensky in Kyiv on Wednesday, a UN spokesman said.

"The secretary-general has just arrived in Poland on his way to Ukraine," said Stephane Dujarric, spokesman for Guterres, in a statement issued on Tuesday.

Guterres and Zelensky will discuss the continuation of the Black Sea Grain Initiative in all its aspects, said the statement.

On July 22, 2022, Russia and Ukraine separately signed a document in Istanbul with Türkiye and the United Nations on grain and fertilizer exports from Ukraine and Russia to ensure supplies to global markets amid the Russia-Ukraine armed conflict.

The deal, due to expire on Nov. 19, 2022, was extended for another 120 days. Guterres has repeatedly called for the deal's further extension.

While in Kyiv, Guterres will also talk with Zelensky about "other pertinent issues," Dujarric said in the statement, noting that it is the UN chief's third visit to Ukraine in the last year.

Guterres will be back to the United Nations headquarters in New York Thursday, according to the statement.
