Poland has arrested a Chinese Huawei employee and a Polish national involved in cyber-business on alleged espionage, Polish media reported, deepening controversy over Western criticism of society Chinese telecommunications.
However, a spokesman for the Polish security services told Reuters that the allegations concerned individual actions and were not directly related to Huawei.
US intelligence agencies claim that Huawei Technologies Co Ltd is linked to the Chinese government and that its equipment may contain backdoors for government spies.
No evidence has been produced publicly and the company has repeatedly denied the allegations. Critics have, however, led several Western and corporate countries to question whether they should allow the use of Huawei's equipment in their telecommunication networks. This has tended relations with Beijing.

Polish state-run TVP TVP said that the security services had conducted searches in Huawei's local offices as well as those of the telecommunications company Orange Polska, where it said Polish public works were being carried out.
The Chinese Foreign Ministry expressed deep concern over the news and urged Poland to treat the case fairly.
Huawei said, "We are aware of the situation and we are looking at it. Huawei complies with all laws and regulations in force in the countries where it operates and requires each employee to comply with the laws and regulations in force in the countries where it is based. "
Orange Polska said that the security agency had gathered Tuesday documents regarding an employee she did not identify. The company added that it did not know if the investigation was related to the professional work of the employee and that it would continue to cooperate with the authorities.
According to TVP, the security services also raided the premises of the Office of Electronic Communications, but the Polish telecommunications regulator denied it.
In December, Canadian authorities arrested a Huawei leader, Meng Wanzhou, at the request of the US authorities, in an investigation into alleged violations of trade sanctions, which caused tensions with China in China. at a time when Washington and Beijing were engaged in a wider trade war.
Western security concerns over Huawei and China's telecommunications equipment company ZTE Corp. relate to China's security intelligence law. Approved in 2017, the law stipulates that "Chinese organizations and citizens must, in accordance with the law, support intelligence activities at the national level, cooperate with them and collaborate with them".
This has raised concerns that the Chinese government may ask Huawei to incorporate backdoors into its equipment, which would allow access to Beijing for espionage or sabotage purposes. . Some experts are also concerned that Chinese intelligence is developing a way to subvert Huawei's hardware.

Norway announced on Wednesday that it plans to join other Western countries in preventing Huawei from building part of the country's 5G telecommunications network.
Maciej Wąsik, deputy director of Polish special services, told the official PAP news agency: "The Chinese national is a business man working in a large electronics company … the Pole is a person known in circles related to cyber-business. "
The arrested pair will be held for three months, PAP reported, quoting the spokesman of the chief of Polish special services.
TVP stated that the Polish national was a former agent of the internal security agency. The agency did not immediately respond to Reuters' requests for comment.
