Donald Trump's apparent 'U-turn' on Huawei ban explained and what happens now

US President Donald Trump surprised many at the G20 Summit in Osaka when he relaxed his ban on American companies doing business with Huawei, which has been at the centre of his trade war with China. The apparent backflip means that businesses like Google and Qualcomm can tentatively continue business as usual with Huawei, without requiring special permission from the US federal authorities. But the White House and Commerce Department haven't yet clarified whether the decision will affect Huawei's use of Google's Android operating system.
