While several law firms have added new lobbying clients in recent weeks, firms have also cut ties with other clients, including Chinese companies.

The terminations come amid increased scrutiny of Chinese companies’ lobbying activities on Capitol Hill and increasing national security concerns by the White House and Congress related to China. At the end of January, the Defense Department released an updated list of names of “Chinese military companies” operating directly or indirectly in the United States, in accordance with the statutory requirement of Section 1260H, according to a press release.
