Mercury is working the Washington beat for Alibaba Group, China’s most valuable technology company, as trade tensions grow between the US and China.

The Omnicom unit is handling technology policy, access to US capital markets and issues related to e-commerce.

President Trump has threatened to sanction China social media companies ByteDance and Tencent, owners of the TikTok video site and WeChat messaging app, respectively.

Alibaba CEO Daniel Zhang told investors on Aug. 20 that his company is keeping a close eye on the “very fluid” US policies toward China.

He reassured Trump that Alibaba poses no threat to the US.

“As the world’s largest e-commerce platform, Alibaba’s primary commercial focus in the U.S. is to support American brands, retailers, small businesses and farmers to sell to consumers and trade partners in China as well as other key markets around the world,” Zhang said on the earnings call.

Alibaba’s mission to “make it easy to do business anywhere” is aligned with the interests of China and the US, added Zhang,.

Mercury’s Alibaba team features Adam Bramwell, chief of staff to Delaware Democratic Senator Chris Coons, a good friend of Joe Biden; Bryan Lanza, communications director for the Trump transition team; and John Lonergan, long-time consultant to former New York Republican governor George Pataki.

Taiwan on Aug. 25 declared Taobao Taiwan, a platform linked to Alibaba, a potential risk to its national security.
