"A Chinese assistant foreign minister has been dismissed from his post and placed under investigation, Beijing said Friday, amid a much-publicised anti-corruption campaign.
It was not clear who was conducting the investigation or exactly what Zhang was alleged to have done.
Zhang previously made headlines for giving a US diplomat a public dressing-down in 2012 over Washington's criticism of a Chinese military garrison in the South China Sea.
"We urge the US side to correct its mistaken ways, respect China's sovereignty and territorial integrity," Zhang told the US embassy's then-deputy chief of mission Robert Wang.
Zhang's rise up the ranks of China's foreign ministry, which he joined in the 1980s, coincided with the growth of Beijing's diplomatic influence alongside its booming economy.
His official globetrotting has in recent years encompassed events in Brazil, the Netherlands and the US, according to the foreign ministry.
The ministry's website showed that Zhang's role as head of the ministry's protocol department, which oversees diplomatic ceremonies, has been temporarily taken up by ministry spokesman Qin Gang.
Zhang's dismissal comes as China's President Xi Jinping presses a much-publicised anti-graft campaign, which has snared several high-profile politicians.
It also follows the mysterious disappearance of China's ambassador to Iceland amid reports he had allegedly spied for Japan.
A Chinese state-run newspaper urged Beijing to say whether envoy Ma Jisheng was a spy after he left Iceland mysteriously in January 2014, with Beijing only telling Reykjavik that he was unable to return for "personal reasons".
China's embassy website at the time contained a link titled "CV of Ambassador", but the resulting page was blank. Beijing has refused to comment on Ma's status."
