Athletes and visitors heading to the 2022 Winter Olympics in Beijing should leave their phones at home and use temporary ones instead, the FBI has urged. The warning comes after a similar one from cyber-security group Citizen Lab. However, China dismissed the concerns and the Chinese government is spending $3.9bn (£2.9bn) on the Games, which take place in and around Beijing. Human rights groups have called on governments to boycott both, over the treatment of Uyghur people in China. DO you support FBI arguments ?
