WASHINGTON (AP) — Chinese President Xi Jinping’s plans to meet with Russian President Vladimir Putin in Moscow next week highlighted China’s aspirations for a greater role on the world stage. But they also revealed the perils of global diplomacy: Hours after Friday’s announcement of the trip, an international arrest warrant was issued for Putin on war crimes charges, taking at least some wind out of the sails of China’s big reveal. The flurry of developments came as the Biden administration watches warily Beijing’s moves to assert itself more forcefully in international affairs.
