Marietje Schaake, International Policy Director at Stanford's Cyber Policy Center, Eurasia Group senior advisor and former MEP, discusses trends in big tech, privacy protection and cyberspace:

The US warned Brazil about China's Huawei equipment in its 5G telecoms network. Would it be possible to ban Huawei in Brazil?

Now in theory, yes, but in practice, that will be very difficult. If not Huawei, the Brazilian mobile network infrastructure is largely sourced from China, and China is the country's most important trade partner overall. But as always, much depends on political leadership. President Bolsonaro, after all, did go along with President Trump in opposing Huawei while he was facing pushback for that decision at home. So the lesson to learn is that it is easier to prevent risky 5G telecoms equipment to come into the country than to cure when it's already there.
