A source close to the news told Campaign Asia-Pacific that Tang signed a departure paper on 21 December. Another source, who used to work for McCann China, reported that Tang had cleared out her desk.
Tang denied the move last Friday and this morning via instant messaging. However, McCann China confirmed the resignation just half an hour before press time via email.
The statement from Jesse Lin, CEO of McCann Worldgroup Greater China, said: "Ame has been with McCann for over 12 years and devoted herself to the success of many clients. I would like to take this opportunity to thank Ame for her energy and hard-working approach, and wish her all the best for her future endeavours. Tang's replacement will be announced in due course."
A series of long-term top managers have left McCann China in the last year, including T.H. Peng, Pratik Thakar, Vincent Pang, Carol Lam, Andy Ho, Canon Wu, and James Yang. David Shen, who also resigned, returned after six months last July to take up the post of president of McCann Healthcare Greater China.
Update, 2:15 pm: McCann has added that Tang will serve until the end of this month.
