The US government's export ban on ZTE has effectively brought the Chinese telecom giant and phone maker to its knees. 

In a Hong Kong Exchanges filing on Wednesday, ZTE told investors that the "major operating activities of the company have ceased" because of the US Commerce Department's export ban. In April, US officials said they were imposing a "denial of export privileges" against ZTE, which means US companies can't sell products and services to the Chinese company.
