June 11 : WuXi AppTec said on Thursday that it has filed a complaint at the United States District Court for the District of Columbia against the Department of Defense for including the company in a list linked to the Chinese military.

The designation could threaten a key revenue stream for the drug contractor and complicate research, manufacturing and supply chains for American pharmaceutical firms.

WuXi AppTec is back on the defense after being added by the Pentagon to an updated list of companies that have ties to the Chinese military.
