It also called on the U.S. government to halt its state-sanctioned campaign against Huawei because it will not deliver cybersecurity.
"This decision threatens to harm our customers in over 170 countries, including more than 3 billion customers who use Huawei products and services around the world", Song said at a news briefing. Just a day after the ban, the Trump administration surprisingly came to the rescue of Huawei by issuing a temporary license that allows US companies to do business with Huawei for three months. "This will also result in tens of thousands of American jobs".
Citing national security risks, the USA government effectively shut the Chinese telecommunications equipment maker Huawei out of the domestic market last week, a shot at China that the Trump administration happened to be taking amid an escalating trade war with Beijing.
The trade dispute between the USA and China is reaching the US courts system.
But Mr Song said the US Government had not shown any evidence that Huawei was a security threat.
"Related Chinese government departments announced on June 1 that because US FedEx did not deliver to the right addresses in China, severely hurting the legal rights and interests of its customers".
China is investigating USA delivery services giant FedEx for "wrongful delivery of packages", Chinese state media reported on Saturday, a day after Beijing warned that it was drafting an "unreliable entity list" of foreign companies.
Song says, "I don't think it is right for any company to intercept or detain individual documents or information".
Huawei's Chief Legal Officer Song Liuping attends a news conference on Huawei's ongoing legal action against the USA government's National Defense Authorization Act (NDAA) action at its headquarters in Shenzhen, Guangdong province, China May 29, 2019. That firm made a similar claim in US district court but lost when the restrictions were upheld.
Song said Washington's use of administrative orders and laws to punish a single company "sets a very risky precedent".
"We normally don't comment on commercial operations on businesses". It has banned government agencies from buying Huawei equipment.
The Chinese firm had in March filed a suit against a United States bill that placed restrictions on it's products.
A hearing on the motion is set for 19 September 2019, approximately one month after the 90-day reprieve.
"Today it's telecoms and Huawei", he said.
FedEx's China branch said May 28 in a post on Chinese social media platform Weibo that the company regrets that this isolated number of Huawei packages was inadvertently misrouted and confirms that "we were not requested by any external party to divert these packages which are in the process of being returned to the shippers". "There is no gun, no smoke but only speculation", Liuping said.
Song Liuping, the firm's legal officer, said the company was due to file the motion for summary judgment on Tuesday.
