A senior Chinese diplomat is being investigated for corruption, China’s foreign ministry says. Zhang Kunsheng has been removed from his position as assistant foreign minister and is being probed for “violating discipline”, a brief statement from the ministry read. President Xi Jinping has vowed to eradicate corruption in China. State media described Mr Zhang as the highest-ranking diplomat to be targeted in the anti-corruption drive. The anti-corruption campaign has netted thousands of officials since it began in 2012, among them former security chief Zhou Yongkang in 2014. The foreign ministry said Mr Zhang was “suspected of violating discipline”, an official euphemism for corruption.
