Ukrainian drones targeted Moscow for a third day on Wednesday, forcing most of the Russian capital's airports to close hours before Chinese President Xi Jinping was due to fly in for a pomp-filled visit that Kyiv has made clear it opposes.

The Trump administration has said it wants to pull apart Russia and China, but the two countries need each other too much.

Chinese President Xi Jinping has arrived in Moscow for a four-day state visit, his 11th to Russia, in a show of strategic solidarity with President Vladimir Putin. The visit is seen as a significant diplomatic boost for Russia as it seeks to counter claims of international isolation following its ongoing war in Ukraine.
