According to US National Security Adviser Robert O'Brian, Huawei is able to access sensitive and personal information wherever its equipment is installed and "by law, must comply with directives of the Chinese Communist Party" making networks using it vulnerable to Beijing's surveillance.
Trump had brought up the security concerns with Prime Minister Narendra Modi during the February visit in a bid to stop Huawei's inroads into India's 5G networks.
Trump told reporters after meeting Modi, "We discussed the importance of a secure 5G wireless network and the need for this emerging technology to be a tool for freedom, progress, prosperity, not to do anything with which it could be even conceived as a conduit for suppression and censorship."
