And this week, HNA canceled its A$280 million ($207 million) debt-funded offer to buy the refrigerated trucking arm of Australia's Automotive Holdings Group Ltd.

Following its now-infamous acquisition spree, the group's financial struggles began to emerge in the middle of a year ago, when the Chinese government began scrutinizing high-profile acquirers such as HNA, Dalian Wanda Group Co. and Anbang Insurance Group Co. It already has sold a more than $1 billion stake in an affiliated timeshare company, Hilton Grand Vacations Inc. Growing into a multinational giant within two decades, the conglomerate now owns assets in numerous industries including aviation, real estate, financial services, tourism, and logistics.
However, HNA started to sell large chunks of its global interests in the wake of a crackdown by Chinese authorities on debt-fuelled financing. In June, HNA sold a bond in China after a rare five-month drought, signaling a crucial source of funding for the conglomerate may be opening up.
