Many US companies do business in China. But their exposure to the country's economy can vary widely from company to company and even from year to year.

Strategy Risks founder and CEO Isaac Stone Fish has compiled a list of companies that have the most exposure to China right now. Here's how Stone Fish describes how his firm compiled its list: "The way that we measured this doesn't just look at business fundamentals, revenue, but also looks at supply chain exposure, looks at their exposure to alleged forced labor or more direct forced labor in Xinjiang or Tibet. And then I think the most important category that's new is partnerships and politics. When you work in China, your relationship with the Communist Party of China is paramount. And we felt that investors, regulators, and the corporates themselves need to have a much better understanding of what companies' relationship with the Communist Party is."

So which company tops Strategy Risks' list? Ford Motor (F). By topping the list, Stone Fish says it doesn't mean the company is the most successful in China or even has the largest market share there rather "it's the cumulation of these various exposure points," adding that "Ford is relatively closely tied to China's economic success or failure, but it also means that Ford is vulnerable to folks in the US government or consumers or other parts of its supply chain that might wonder why it's focusing so much on China and what that means for its business in the United States or elsewhere in the world."
