US President Donald Trump is looking to require next-generation 5G cellular equipment used in the United States to be designed and manufactured outside China, the Wall Street Journal reported on Sunday, citing people familiar with the matter. As part of a 150-day review that started after cybersecurity concerns in the United States, officials are asking telecom equipment makers if they can develop US-bound hardware including cellular-tower electronics as well as routers and switches, and software outside of China, the WSJ reported. In May, the Trump administration took aim at China's Huawei Technologies Co Ltd, banning the firm from buying vital US technology without special approval and effectively barring its equipment from US telecom networks on national security grounds. The talks are still in informal stages, the WSJ said, and any executive order calls for only a list of proposed rules and regulations by the 150-day deadline, in October, so any decision could take years to adopt.
