London (CNN Business) 1. FedEx lawsuit: FedEx (FDX) is suing the US government, claiming it shouldn't be required to enforce federal export bans like the one targeting Huawei.

Policing the contents of packages "is a virtually impossible task, logistically, economically, and in many cases, legally," the company said.

The lawsuit comes after FedEx mishandled deliveries for Chinese smartphone and telecom equipment company Huawei.

Beijing launched an investigation into FedEx as a result — a warning sign for multinational companies as the trade fight between the United States and China drags on.

China is in the process of drawing up a blacklist of foreign companies, individuals and organizations. Investors are worried FedEx will be included.
