KYIV--U.S. President Joe Biden walked around central Kyiv on an unannounced visit on Monday, promising to stand with Ukraine as long as it takes, on a trip timed to upstage the Kremlin ahead of the one-year anniversary of Russia's invasion.
Biden, in his trademark aviator sunglasses, and President Volodymyr Zelenskiy, in green battle fatigues, walked side-by-side to a gold-domed cathedral on a bright winter morning pierced by the sound of air raid sirens.
"When (Russian President Vladimir) Putin launched his invasion nearly one year ago, he thought Ukraine was weak and the West was divided. He thought he could outlast us. But he was dead wrong," Biden said. "The cost that Ukraine has had to pay is extraordinarily high. Sacrifices have been far too great. ... We know that there will be difficult days and weeks and years ahead."
Outside the cathedral, burned-out Russian tanks stand as a symbol of Moscow's failed assault on the capital at the outset of its invasion, which began on Feb. 24. Its forces swiftly reached Kyiv's ramparts - only to be turned back by unexpectedly fierce resistance.
Since then, Russia's war has killed tens of thousands of Ukrainian civilians and soldiers on both sides, cities have been reduced to rubble, and millions of refugees have fled. Russia says it has annexed nearly a fifth of Ukraine, while the West has pledged tens of billions of dollars in military aid to Kyiv.
"This visit of the U.S. president to Ukraine, the first for 15 years, is the most important visit in the entire history of Ukraine-U.S. relations," Zelenskiy said.
Biden traveled to Ukraine's capital by overnight train from Poland, arriving after roughly 10 hours at 8 a.m. on Monday, before returning there the same way, leaving just after 1 p.m., according to a White Pool report by a Wall Street Journal reporter. He arrived at the Polish border city of Przemysl that evening. Biden is scheduled to meet Poland's President Andrzej Duda, along with other leaders of countries on NATO's eastern flank, in Warsaw.
While Biden was in Kyiv, the State Department announced a further $460 million in U.S. aid to Ukraine, including $450 million worth of artillery ammunition, anti-armor systems and air defense radars, and $10 million for energy infrastructure. The European Union's foreign policy chief, Josep Borrell, said the bloc would approve more sanctions before the anniversary of the conflict, which Russia says is a "special military operation."
Russia was notified before Biden's departure, officials in Washington and Moscow said, apparently to avoid the risk of an attack on Kyiv while he was there. The trip took place a day before Putin was due to make a major address on Tuesday, setting out aims for the second year of what he now calls a proxy war against the armed might of Washington and the trans-Atlantic military alliance NATO.
"Of course for the Kremlin this will be seen as further proof that the United States has bet on Russia's strategic defeat in the war and that the war itself has turned irrevocably into a war between Russia and the West," said Tatiana Stanovaya, a Russian political analyst.
Russia has sent thousands of conscripts into Ukraine for a winter offensive but has secured only scant gains so far in assaults in frozen trenches up and down the eastern front in recent weeks. Kyiv and the West see it as a push to give Putin victories to tout a year after he launched Europe's biggest war since World War Two.
Moscow received its own signal of diplomatic support on Monday, with Chinese Foreign Minister Wang Yi expected for talks. In public, China has remained neutral over the conflict despite signing a "no limits" friendship pact with Russia weeks before the invasion.
Washington has said in recent days it is concerned Beijing could begin supplying Moscow with arms. Chinese Foreign Ministry spokesperson Wang Wenbin said the United States was "in no position to make demands of China".
A diplomatic source speaking on condition of anonymity told Reuters that Wang Yi would discuss Chinese ideas for a political settlement of the war. Ukraine says any diplomatic solution requires the withdrawal of Russian forces from its territory.
