You’ve Never Heard of HNA Group. Here’s Why You Will.

The $53 billion Chinese conglomerate already owns a company near you.

On a warm summer night in Paris, hundreds of executives, bankers, diplomats, and French officials walk the red carpet snaking up the steps of the Petit Palais museum—a sumptuous Beaux Arts building in the heart of the French capital, with sculptures and paintings set around a manicured garden. Under 200-year-old frescoes, the guests dine on lobster, duck, and white-chocolate mousse, prepared by a top French chef, washed down with grand cru Bordeaux, and topped off with entertainment from the Peking Opera. Three large red letters affixed to the ornate gates offer a clue about who’s throwing the invitation-only affair: HNA.

To the hundreds of people passing by, the name HNA probably means nothing. But to the business world at large, the presence of those three letters is another sign—if any is needed—that a little-known Chinese conglomerate with provincial roots has, in just a few years, transformed into a powerful global player with tentacles stretching across the planet.

HNA Group, headquartered in Hainan in southern China, still lacks the brand-name status it eagerly seeks. That’s despite the fact that it has plowed tens of billions of dollars into buying up foreign assets since 2015, on every continent—including $5.66 billion in just the past six months, according to the tracking firm Dealogic. By the company’s estimation, its investments in the U.S. alone have reached $35 billion.

Over the past two years, about $1 trillion has flowed out of China, as Chinese individuals and companies, having made fortunes at home and with state-owned banks willing to lend, invested elsewhere. Among those companies, one of the most aggressive has been HNA. Its dealmaking in some ways highlights how a mere handful of Chinese groups have snapped up dozens of Western assets, especially since the 2008 economic crisis, while at the same time leaving unanswered questions over ownership and transparency.

In the case of HNA, its executives have crisscrossed the globe in a frenetic buying spree, making deals through a labyrinth of subsidiaries in China and abroad. The purchases have included household names for Americans and Europeans. Among them are Minnesota-based Carlson Hotels—owner of the Radisson and Park Plaza hotels—which HNA bought outright last December for an undisclosed sum. In March of this year, it bought 25% of Hilton Worldwide Holdings hlt , the hotel group, from Blackstone for $6.5 billion. And in May it increased its stake in Deutsche Bank to become its biggest shareholder, with its stake worth about $3.7 billion.
