HONG KONG — U.S. hospitals and state officials face desperate shortages of the masks, ventilators and other gear they need to fight the coronavirus. Chinese factories can make the equipment and sell it to them, but huge obstacles stand in the way — and Washington’s stumbles and growing hostility with Beijing aren’t helping.

Now some of China’s elite — and others with big stakes in keeping the U.S.-China relationship alive — are stepping in to help.

An ad hoc network of companies, wealthy individuals, academics and former diplomats has emerged to help the United States get the Chinese-made goods it needs to save patients and protect front-line workers — and, perhaps, help polish China’s dented image along the way. They are trying to navigate snarled supply chains, connect wary buyers and sellers and help overwhelmed local officials in desperate need of equipment.

The group includes people like Jack Ma and Joseph Tsai, the co-founders of Alibaba, the Chinese e-commerce giant; Marc Benioff, a co-founder of Salesforce, who struck a pact with Alibaba last year to sell its services in China; and Yichen Zhang, the chairman of Citic Capital, a major Chinese investment firm affiliated with a state-run conglomerate.
