Wouldn't it be wiser, fairer, and less xenophobic/nationalistic appearing to simply require particular audit/compliance/certification requirements and then disallow nonconforming equipment/systems?
Because if something can't be sold under brand X specifically, then brand Y will be invented to circumvent it, hence it's a superficial and ineffective process to forbid a brand by name.
Rigorous audit and compliance processes should assure products are tested, supported, and hopefully minimize the risks of hostile anti-functionality.
Perhaps some key tech bits are so fundamental that they should be grown domestically without necessarily a huge profit motive to offer reliable components for strategic infrastructure.
