Lol, so Huawei is violating the US laws. You are so braindead that you didn't even know this is not only about "spying". There are tens of cases that's been investigated since 2006-2007, which also include financial crimes and corruption(trying to bribe the US authorities).
Here is the list of Huawei crimes.:
13 counts brought in the Eastern District of New York state:
(1) and (2) Conspiracy to commit bank fraud: Between around November 2007 to May 2015, Huawei, Skycom, and Meng Wanzhou allegedly conspired to defraud “US Subsidiary 1,” a subsidiary of a global financial institution identified only as “Financial Institution 1,” by misrepresenting Huawei’s relationship with Skycom to clear more than $100 million of transactions to it through the United States. According to a New York Times report, the financial institution is HSBC (paywall), which is not accused of any wrongdoing. The alleged misrepresentations include a PowerPoint presentation Meng gave in 2013 that described the relationship between Huawei and Skycom as “business cooperation” and said her presence on its board was to strengthen compliance. The second count, which covers the period between August 2017 to the present, refers to dealings with a financial institution called “US subsidiary 4” and is against Huawei and an unidentified defendant or defendants.
(3) Conspiracy to commit wire fraud: From about November 2007 to May 2015, Huawei, Skycom, Meng Wanzhou, and others allegedly conspired to transmit communications to defraud four “victim” financial institutions.
(4) Bank fraud: Between around November 2007 to May 2015, against Huawei, Skycom, Meng Wanzhou, and others allegedly obtained funds in the custody of “US Subsidiary 1” (possibly HSBC) with false representations.
(5) Bank fraud: Between August 2017 and the present, Huawei and unidentified defendant(s) allegedly obtained funds in the custody of “US Subsidiary 4” with false representations.
(6) Wire fraud: Between around November 2007 to May 2015, against Huawei, Skycom, Meng Wanzhou, and others allegedly made misrepresentations via email about the relationship between Huawei and Skycom, and about Huawei’s compliance with US and US regulations, which caused wire transfers to be sent by the victim financial institutions through the United States.
(7) Conspiracy to defraud the United States: Around July 2007 and the present, Huawei and Skycom, and others allegedly obstructed the operations of the Office of Foreign Assets Control (OFAC), an agency that enforces US sanctions laws, with deceitful acts. The alleged acts included “Individual 1” [identified as Huawei’s founder but not named] telling FBI agents that Huawei activities don’t violate US export laws, and that Huawei had not dealt directly with any Iranian company. They also included testimony by a Huawei senior vice president to the US Congress that Huawei’s business in Iran did not violate any rules or regulations, including related to sanctions. [Charles Ding, a senior VP with the company, testified before Congress on Sept. 13, 2012.]
(8) Conspiracy to violate the International Emergency Economic Powers Act (IEEPA): The act gives the president authority to address extraordinary threats to US national security, foreign policy, or the economy. The US has declared Iran such a threat using this act, most recently in March 2018, leading OFAC to prohibit the export from the US or by a US person of goods, technology and services to Iran without its permission. Between November 2007 and November 2014, Huawei, Skycom and others allegedly conspired to cause the supply of US financial services to Iran without obtaining permission. The penalty is up to a $1 million fine or up to 20 years in prison.
(9) IEEPA violations: Between around November 2007 and November 2014, Huawei, Skycom and others allegedly caused the export of US financial services to Iran without an OFAC license.
(10) Conspiracy to violate IEEPA: Between 2008 and 2014, Huawei, Skycom and others allegedly conspired to cause the export of telecommunications services provided by a US citizen to Iran without OFAC permission.
(11) IEEPA violation: Between 2008 and 2014, Huawei, Skycom and others allegedly caused the export of telecommunications services provided by a US citizen to Iran without OFAC permission.
(12) Conspiracy to launder money: Between around November 2007 and November 2014, Huawei, Skycom, and others allegedly conspired to carry out wire transfers between the US and other places to promote the unlawful activity of violating the IEEPA.
(13) Conspiracy to obstruct justice: Between around January 2017 and the present, Huawei and Huawei USA allegedly conspired to obstruct a federal grand jury investigation in the Eastern District of New York by moving witnesses with knowledge about the Iran dealings to China, and to destroy and conceal evidence in the Unites States of the Iran business.
10 counts brought in the Western District of Washington state:
(1) Theft of trade secrets conspiracy: Between June 2012 and September 2014, Huawei Device and Huawei Device USA allegedly conspired to steal and convey trade secrets belonging to Bellevue, Washington-based T-Mobile, related to Tappy, a robotic system for resting phones. These included asking T-Mobile engineers detailed questions about its specifications, taking unauthorized photos of the robot, gaining unauthorized access for a Huawei engineer from the China office to a T-mobile lab, and attempting to steal a robot arm, at the direction of Huawei China. Huawei since 2010 had an agreement to supply phones to T-Mobile and its US-based engineers had access to T-Mobile facilities for testing. The indictment also alleges that Huawei attempted to mislead T-Mobile by saying the engineers in the US took inappropriate actions of their own, while at the time the company had a bonus program for employees who posted confidential information form other companies on an internal website.
(2) Attempted theft of trade secrets
(3)-(9) Wire fraud: Huawei employees transmitted seven emails allegedly related to the plan to defraud T-Mobile of its trade secrets.
(10) Obstruction of justice: Between June 2013 and September 2014 Huawei allegedly attempted to obstruct and influence the civil case brought by T-Mobile against Huawei, and a grand jury hearing in Washington.
And this isn't the full list :/
Also China didn't "ban" some American products, they blocked it, there is a difference in terms of law. How come they violate the laws of China, but yet can have offices and legally operate there? :))) Google had an office for years in China(then moved to Hong Kong) while many of their prdocuts were banned. Interesting law China has :))))
