LONDON — Company filings show that Trump-affiliated data-mining firm Cambridge Analytica has a link to a Chinese security and logistics company run by Erik Prince, the former mercenary who founded private military company Blackwater.

British corporate records show that Alexander Nix, the suspended chief executive of Cambridge Analytica, is also director of a company called Emerdata Ltd. that was incorporated in August 2017.

Other Emerdata directors include people associated with Cambridge Analytica, along with Johnson Ko Chun Shun, who was appointed in January.

Ko is also deputy chairman of Hong Kong-based Frontier Services Group, whose chairman is Prince.

FSG has attracted attention because of concerns Prince plans to provide special forces veterans to assist Chinese companies investing in risky locations overseas.

China’s biggest state-owned company, Citic, is a major FSG shareholder.
