The Public Affairs Director, Huawei, Austin Zhang stated that there is no valid reason for the Polish government to keep the company out of its upcoming 5G network development.
In the letter, Ryan Ding, president of Huawei's carrier business group, stated that the company "has never and will never" use its equipment to assist espionage activities for the Chinese government.
It comes amid growing worldwide concerns over Huawei, after the US, Australia and other western governments effectively barred the company from participating in the roll-out of next generation 5G telecom equipment.
Of late, concerns over foreign companies or vendors helping US enemies to infiltrate sensitive computer systems in the country are high after alleged Russian involvement in the 2016 election.
The unit's most recent report cited a lack of progress in addressing previous concerns, but Huawei has promised to remedy this with a $2 billion investment over five years.
Ding also addressed "concerns about China's national intelligence law" by asserting that there is no law by which the Chinese authorities can compel IT firms to "install backdoors" in their technology to enable covert data-gathering.
Abraham Liu reiterated that Huawei has not and would never harm the interests of customers or countries.
Huawei, the global networks market leader with annual sales exceeding US$100 billion, faces worldwide scrutiny over its ties with the Chinese government and suspicion that Beijing could use its technology for spying.
Huawei defended itself in a letter to United Kingdom lawmakers made public this week, saying that it would take up to five years to see "tangible results" in upgrading its systems. Australia, New Zealand and Japan have all banned Huawei as a wireless network provider over similar security concerns.
BT said in December that it would not buy Huawei equipment for the core of its next generation 5G network, which launches this year in 16 United Kingdom cities.
'There is no evidence indicating that our equipment posed a security threat, no matter in Thailand or globally, ' Huawei Thailand said in a statement to Reuters on Friday.
The executive also said that Huawei would open a "cyber security centre" in Brussels next month that will show that the company is "part of the solution, not part of the problem".
The US Justice Department has charged Huawei with conspiring to violate US sanctions on Iran and with stealing robotic technology from T-Mobile.
Its chief financial officer Meng Wanzhou was arrested in Canada in December at Washington's request.
