Huawei to sell 51pc stake in undersea cable business after US trade blacklist
- Huawei Marine Networks is a joint venture with Britain’s Global Marine Systems

Huawei Technologies is selling its majority slice of its global submarine cable division, exiting the business of laying undersea piping for the internet just weeks after the Trump administration blocked the Chinese firm from buying American technology.
The corporate parent of Huawei is selling its 51 per cent of Huawei Marine Networks to Hengtong Optic-Electric Co, a Jiangsu-based optical-cable manufacturer, according to a stock exchange filing. The deal is not formalised and subject to change, Hengtong said in the filing.
Hengtong, whose Shanghai-listed shares have been suspended from trade, did not disclose the size of the deal.
A Huawei spokesman declined to comment. Huawei Marine and Hengtong did not immediately reply to calls and emails from Bloomberg News.
President Donald Trump’s administration has targeted Huawei for months, first encouraging allies to ban the Chinese company’s equipment from their networks and then putting Huawei on an export blacklist that prohibits it from buying American software and components.
