TV channel TVP said the two individuals were arrested on Tuesday after the Huawei and Orange Polska offices were searched. Huawei is facing increased spying accusations from the United States and its allies.
Polish security services have charged a Chinese manager at tech giant Huawei in Poland and a Polish former intelligence officer with espionage against the country on behest of China. Both are accused of espionage.
National media reported that two people had been arrested, one of whom is reported to be a sales director at the Chinese hardware supplier.
The Polish suspect in the case, Piotr D., was an officer in the Internal Security Agency until 2011, according to TVP Info, which says he was an adviser to the head of the special service who also had expertise about the network Poland's government uses to share sensitive information.
Wasik said that the Chinese suspect was a businessman working for a major electronics corporation and that the Pole was "known in circles associated with cyber-business affairs".
But the criticism has led several Western countries and companies to look into whether they should allow Huawei's equipment to be used in their telecoms networks, straining relations with Beijing.

He also released the song Mona (I Need You Baby) and toured the United Kingdom and Europe with his band Check 1-2. It is not clear if the charges relate to the allegations made against him by the Rocky Horror Show actresses.
Huawei told the BBC it had no immediate comment.
Huawei has been blocked in the US since 2012 after the House Intelligence Committee report found that using the company's technology could pose a security risk.
If convicted, they could face up to 10 years in prison.
"We have no comment for the time being. Huawei complies with all applicable laws and regulations in the countries where it operates, and we require every employee to abide by the laws and regulations in the countries where they are based".
The allegations were that Huawei was using its kit to spy on other governments - claims the firm has strenuously and repeatedly denied.
In December, Canadian authorities arrested a top Huawei executive, Meng Wanzhou, at the behest of US authorities as part of an investigation into alleged violations of USA trade sanctions.
