The Palm company behind the takeover, backed by investor Guochuan Lai are worth an estimated £1.8 billion.
That will certainly help the Baggies in their efforts to strengthen in the transfer market this summer, and is an ominous sign for Leeds United, who are attempting to resists the club's advances for player of the year Charlie Taylor.

The Sun reported in late July that West Brom were poised to make an offer for Taylor, who then handed in a transfer request.
This was rejected by Leeds, despite the left-back having only one year left on his contract.
Leeds issued a statement on their website declaring Taylor not for sale, and with one month left of the transfer window, they would be confident of digging in.
Yet West Brom's new wealth could make it hard to hold firm, and the Baggies may well come back with an improved offer which is too much for Leeds to resist.

Getting a good price for Taylor would be welcome for Leeds if they do cash in, but the Whites will not want to receive it when it is too late to go and spend it.
The hope for Leeds should be that West Brom could now set their sights higher than Taylor, but with the left-back reportedly so admired by the club, it is likely to result in a renewed push to prise him away from the Championship club.
