text:  This is The World. I'm Marco Werman. The leader of Hungary, Viktor Orban, made a surprise visit to Ukraine today and met with President Volodymyr Zelensky. It was Orban's first visit to Kyiv since Russia's full-scale invasion. In the past, he's taken a decidedly pro-Russian stance on the war in Ukraine. Orban's visit coincides with Hungary taking over the rotating presidency of the European Union this week. We asked Yaroslav Trofimov if the surprise trip is symbolism or substance. He reports on Ukraine for The Wall Street Journal.
