New UK Foreign Secretary David Cameron visits Odesa with Ukraine counterpart Kuleba

David Cameron has traveled to the Ukrainian port of Odesa in his first overseas trip as Britain’s new foreign minister.

He has pledged that the U.K. will continue providing military support until Ukraine is victorious in its war with Russia.

Cameron, a former prime minister who was appointed this week in a Cabinet shuffle, says he wanted to make the trip to Kyiv his first diplomatic visit, and he met with Ukrainian President Volodymyr Zelenskyy on Wednesday.

The historic city on the Black Sea is home to the nation's busiest ports and serves as one of the main shipping points for Ukrainian grain destined for world markets.

The city and ports have come under fire since Russia in August declined to renew a deal allowing Ukraine to safely export grain via the Black Sea.

Cameron was shown how Ukraine is fighting back against Russia in the Black Sea to ensure that grain is still reaching countries in the developing world, his office said, though it provided no details.

Since the collapse of the grain deal, a new corridor in the Black Sea has allowed 91 ships to export cargo.
