What's happening now in the semiconductor equipment sector is almost an exact replay of what happened in the telecom equipment sector in the 1990's. Huawei and ZTE would not have had the chance to develop into the telecom equipment giants that they are today without the export restrictions the US imposed on telecom equipment back in the 1990's.And to add salt to injury once the have those solutions they will sell those to the Europeans and the US, directly or indirectly, to much of the horror of US and Europeans companies that once dominated the Chinese market.
It's ironic that a firm that owes so much of its success to US export restrictions in the 1990s is now one of the main causes of the angst behind the US export restrictions of today.
