he says the u.s. claims about the national security are unfounded. here's what he has to say. why is huawei being singled out? there's no huawei equipment in the u.s. networks. has that made the u.s. networks totally safe? if not, how can they tell other countries that your networks are safer than huawei. that's why we want to make clear our stance by suing the u.s. government. >> reporter: now, it's not just the united states going after huawei simply for huawei and its activities, or would-be activities in the u.s. it's also a concerted campaign by the united states to get other countries, other governments around the world, to also shun huawei products. you had the vice president, the secretary of state basically going around if you work with huawei, buy their products, your relationship with the united states will get worse. and we saw an example of that this week in germany, where the u.s. told the germans, if they buy huawei products, they would see limited intelligence sharing with the americans.
