While it may be one of the world's best-known Chinese technology companies, few tech firms have stirred up as much controversy as Huawei.
The Chinese conglomerate, a global leader in 5G technology, telecommunications equipment and smartphones, continues to face scrutiny from Western governments and lawmakers over its role in global telecoms infrastructure.
Most notably, the firm has faced allegations, primarily from the United States and its allies, that its wireless networking equipment could pose national security risks or potentially enable surveillance by the Chinese government.
These concerns intensified with Huawei's involvement in the development of 5G wireless networks and have led several countries to restrict or prohibit the use of Huawei equipment in their telecoms infrastructure.
But what really is the problem with Huawei? And why have the US and several other Western governments restricted Huawei technology? For that, we’ll need to start from the beginning.
This article explores the Huawei controversy, including the security concerns, sanctions and legal disputes that led to the company being restricted in the US and excluded from 5G networks in several other countries.
What is Huawei?
Huawei is a Chinese multinational technology company headquartered in Shenzhen. Founded in 1987, Huawei has rapidly grown to become one of the world's largest providers of telecommunications equipment, 5G technology and consumer electronics.
Known for its innovative products and competitive pricing, Huawei has gained significant market share in various sectors, including smartphones, networking equipment and cloud computing.
The company's flagship smartphones, such as the Mate and P series, have garnered widespread recognition for their advanced features and performance. Although US sanctions significantly affected Huawei's global smartphone business, the company has since staged a major comeback in China and continues to compete in the global smartphone market.
However, Huawei has also faced intense scrutiny in recent years. Western governments, particularly the United States, have raised concerns about its potential ties to the Chinese government and the national security risks they believe its telecommunications equipment could pose.
In response, Washington and several of its allies have imposed sweeping restrictions on Huawei as part of a broader effort to reduce security risks associated with Chinese telecommunications technology.

When Did the Huawei Controversy Begin?
The controversy surrounding Huawei escalated in the 2000s when US officials began raising concerns that Huawei-made telecom equipment could potentially enable unauthorised access to sensitive communications and infrastructure.
One reason cited for these concerns was that Huawei founder Ren Zhengfei previously served as an engineer in China’s People’s Liberation Army.
The Committee on Foreign Investment in the United States also scrutinised a deal by Bain Capital to acquire 3Com with Huawei as a minority investor, and Huawei's attempt to acquire the virtualisation firm 3Leaf Systems, due to national security concerns.
However, it wasn’t just security concerns that sparked controversy around Huawei. Throughout the 2000s, US companies and other telecom firms also accused Huawei of intellectual property and trade secret theft.
This included Cisco’s 2003 lawsuit alleging that Huawei had copied elements of its networking software and documentation. The case was eventually settled out of court after Huawei removed the contested material.
Then, in 2017, a US jury found Huawei liable for misappropriating trade secrets from US telecoms company T-Mobile. In 2020, the US Department of Justice also charged Huawei with racketeering conspiracy and conspiracy to steal trade secrets.
According to the indictment, the alleged violations allowed Huawei to reduce research and development costs and gain an unfair competitive advantage.

What Are the Biggest Huawei Controversies?
1. Intellectual Property Theft Allegations (2003)
In 2003, Cisco Systems accused Huawei of infringing its intellectual property. Cisco alleged that Huawei had copied elements of its source code, documentation and other proprietary material.
Huawei disputed aspects of the allegations, and the case was eventually settled out of court after Huawei removed the contested material.
2 . U.S. House Intelligence Committee Concerns (2012)
In 2012, the US House Intelligence Committee released a report expressing concerns about the potential security risks posed by Huawei and ZTE.
The report suggested that equipment supplied by the companies could potentially be exploited for espionage or other malicious activity.
The committee recommended that US government systems and contractors avoid using equipment from Huawei and ZTE, citing national security concerns.
3. U.S. Department of Justice Investigation (2016)
In 2016, US authorities investigated Huawei over whether it had violated US sanctions involving Iran.
The investigation later contributed to criminal charges alleging that Huawei and its executives misled financial institutions about the company's business dealings in Iran.

4. Global Ban on Huawei 5G Equipment (2018 - 2019)
In 2018, the US government began urging allies to restrict Huawei from their 5G networks, arguing that its equipment could present national security and espionage risks.
Several countries subsequently introduced restrictions. Australia prohibited Huawei from participating in its 5G network, Canada prohibited Huawei and ZTE 5G equipment, and the UK requires Huawei equipment to be removed from its 5G networks by the end of 2027.
5. Arrest of Meng Wanzhou (2018 - 2021)
In 2018, Huawei's CFO, Meng Wanzhou, was arrested in Canada at the request of the United States. US prosecutors accused Meng of misleading financial institutions about Huawei's business dealings in Iran.
Meng spent nearly three years under house arrest in Canada before being released in September 2021 after reaching a deferred prosecution agreement with US prosecutors. Her arrest contributed to a major diplomatic dispute involving China, Canada and the United States.
6. Entity List and Further Sanctions (2019 onwards)
In 2019, the US Department of Commerce added Huawei to its Entity List, restricting US companies from supplying certain technologies to the company without government authorisation.
The US subsequently tightened restrictions affecting Huawei's access to semiconductors manufactured using US technology. These measures significantly disrupted Huawei's supply chain and smartphone business, although the company has since developed alternative technologies and rebuilt parts of its consumer business.

Is Huawei Banned?
Huawei is not subject to one single worldwide ban. Instead, different countries have imposed varying restrictions on the company, particularly around 5G and telecommunications infrastructure.
In the United States, the Department of Commerce added Huawei and numerous affiliates to its Entity List in 2019, restricting their access to US technology without government authorisation. US authorities have also imposed restrictions on the approval and use of certain Huawei telecommunications equipment.
Other countries have taken different approaches. The UK has ordered Huawei equipment to be removed from its 5G networks by the end of 2027, while Australia and Canada have also restricted Huawei from their 5G telecommunications infrastructure.
These measures have significantly limited Huawei's access to some Western telecoms markets. However, Huawei continues to operate internationally and remains a major global telecommunications technology company, with a particularly strong presence in China and other markets.
Why Was Huawei Banned in the US?
The main reason for US restrictions on Huawei is concern that its telecommunications equipment could pose a national security risk or potentially be exploited for surveillance or espionage by the Chinese government.
US officials have argued that Chinese laws and Huawei's relationship with the country could potentially allow Beijing to compel the company to assist intelligence activities. Huawei has repeatedly denied that it would spy on behalf of the Chinese government and has disputed allegations that its equipment poses an unacceptable security risk.
The US government has argued that Huawei technology could potentially create risks for critical infrastructure, communications and sensitive data. These concerns contributed to Huawei being placed on the US Entity List in 2019 and to subsequent restrictions on its access to US technology.
Alongside national security concerns, Huawei has also faced allegations and criminal charges relating to trade secret theft and violations of US sanctions against Iran.
Security concerns surrounding Huawei have also influenced policy elsewhere. Australia, Canada and the United Kingdom are among the countries that have imposed restrictions on Huawei equipment in their 5G networks.
These measures are intended to protect the security and resilience of national telecommunications infrastructure. However, the restrictions have also attracted criticism.
Huawei has consistently rejected allegations that it facilitates Chinese government espionage. Critics of the restrictions have also argued that excluding major Chinese suppliers could reduce competition and increase the cost of telecommunications infrastructure, while supporters maintain that the potential national security risks justify the measures.
