FBI Director Christopher Wray said the cases "expose Huawei's brazen and persistent actions to exploit American companies and financial institutions, and to threaten the free and fair global marketplace".
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.
In a January 28 afternoon press conference, law enforcement officials announced a series of charges against Chinese telecommunications firm Huawei ranging from fraud to money laundering.
Last month, Meng was detained in Canada at the behest of the US Justice Department over claims of doing business with Iran, in violation of US sanctions. Meng's arrest sparked outrage in China, which called for her immediate release and condemned the move as a USA - led effort to thwart the telecom giant and constrain China's global ambitions.
A 10-count indictment alleges Huawei stole trade secrets from T-Mobile beginning in 2012.
The United States on Monday charged China's Huawei Technologies Co Ltd, its chief financial officer and two affiliates with bank and wire fraud to violate sanctions against Iran in a case that has added to tensions with Beijing.
The charges follow the December 1 arrest of Huawei CFO Wanzhou Meng, who faces the possibility of decades in jail. "To the detriment of American ingenuity, Huawei continually disregarded the laws of the United States in the hopes of gaining an unfair economic advantage".
Huawei and its Hong Kong-based affiliate Skycom Tech are charged with several counts of bank fraud and wire fraud, as well as violations of the International Emergency Economic Powers Act and conspiracy to commit money laundering. Apart from the trade dispute, the USA and China are competing for control over 5G infrastructure, which both countries believe is key to their economic and military success.
The U.S.is asking that the Canadian authorities extradite Meng. Huawei has been working to displace Samsung as the biggest smartphone maker in the world, while at the same time the United States has been aggressively working to convince allies to ban use of Huawei technology over fears that the company's close ties to China's central government mean the company's devices could be used to spy on consumers.
