“Our agencies and clients already work with them as they have 70 to 80 per cent market share,” said WPP China strategy director Scott Spirit (pictured).
He added that the deal fulfils two objectives for WPP.
“One is the financial return and, by having a stake in it, it will bring it a lot closer to all of our agencies.
“We will have a board observer and we hope to be involved with helping them develop and test new products.”
Spirit declined to comment on either the size or value of the stake.
