Chinese hi-tech researchers ‘told not to travel to US unless it’s essential’

It's reported that the US was considering issuing a warning to US citizens about travelling to China in the wake of Huawei case.

Chinese researchers working in sensitive hi-tech sectors have been warned not to take any unnecessary trips to the United States, a source says, as unease grows in the business community following the arrest of a tech executive in Canada.

Staff at a research agency were also told in an internal memo that if they did have to travel to the US, they should remove any sensitive information from their mobile phones and laptops, according to the source who was speaking on condition of anonymity.
