Foreign ministers of the Group of Seven (G7) leading economic powers have warned that those helping Russia wage war in Ukraine would face "severe costs" as they offered a united front on another key policy challenge: China. After two days of talks in the Japanese mountain resort town Karuizawa, the top diplomats unveiled no new sanctions on Moscow over its invasion but pledged to crack down on those helping Russia evade the measures and acquire weapons. Their final statement sparked a furious reaction from China, which said it had been "maliciously slandered and smeared."
