By buying a profit-rich gaming company, they can play the multiple game, and lower their P/E multiple in China, thus looking "cheap".
In general, gaming companies have been trading at fairly low multiples (King was trading for a while at multiples known for steel mills shortly before their bankruptcy), based on the assumption that the business is hit driven and the life cycle of a hit game is rather short. Yet Supercell has been defying the odds for quite some times now...
So who knows... playing the multiple game might turn out a much better deal long term.
