The only one I can name off the top of my head is Apex Digital (b/c it was HQ'd close to where I grew up). Apex was competing with a Chinese state-owned agency and rejected a buyout offer. Chinese officials arrested its CEO on fraud charges and tried to sieze the company's Chinese operating assets to give to the Chinese company. Eventually, Apex went bankrupt fighting the case.

There are many more; the common thread is usually that these companies are competing with Chinese companies.
