The United States Justice Department has unsealed two indictments against China's Huawei Technologies, several of its subsidiaries and its chief financial officer Meng Wanzhou.
The cases accuse the company of everything from bank and wire fraud to obstructing justice and conspiring to steal trade secrets from T-Mobile US Inc.
The charges add to pressure on Huawei — the world's biggest telecommunications equipment maker — from the United States Government, which is trying to prevent American companies from buying Huawei routers and switches and is pressing allies to follow suit.
Ms Meng, the daughter of Huawei founder Ren Zhengfei, was arrested in Canada last year over alleged violations of US sanctions on Iran.
The US said it would proceed with her formal extradition, a move certain to ratchet up tensions with China.
More to come.
