The Papua New Guinea opposition is questioning the links between Telikom PNG and Chinese owned Huawei Technologies.
Both companies have signed a deal to build the country's broadband network.
But the opposition caucus is calling on the government to tell the people if they have done a full and proper assessment of Huawei because of the company's reported involvement with the Chinese military and Iran.
The opposition leader, Belden Namah, says their concerns follow similar objections raised by a group of US Republican lawmakers.
The telecommunications agreement will see the technology extended to more than 80 thousand premises, allowing faster and more reliable fixed and mobile broadband across PNG.
