Chinese conglomerate HNA Group has added news media to its recent string of acquisitions by acquiring an 80 percent stake in a media company in Beijing that runs the website of Caijing Magazine, one of the most popular and influential Chinese business magazines.

HNA's business now spans aviation, finance, real estate, logistics, hospitality, tourism and ecological technology. And it is adding news media to its portfolio.

HNA did not respond to a request for comment on Tuesday. But an employee at Caijing Magazine who wished to remain anonymous confirmed the equity acquisition, and said that the editorial work of the magazine has stayed independent and was not affected.
