US semiconductor equipment makers rose in premarket trading following a Bloomberg News report indicating that an additional round of US restrictions on semiconductor equipment sales to China might be less severe than previously anticipated. 

People familiar with trade policy said the new restrictions could debut as soon as next week. The measures were part of a multi-month deliberation by top US officials, negotiations with allies in Japan and the Netherlands, and lobbying by US chip equipment makers who've cautioned that stricter measures would harm the industry. 

Here are the key differences between the latest proposal and earlier drafts, according to Bloomberg, citing those familiar with trade policy:

The first is which Chinese companies the US would add to a trade restriction list. The US had previously considered sanctioning six suppliers to Huawei Technologies Co. — the telecom giant at the center of China's tech industry — and officials are aware of at least a half dozen more, the people said. But they now plan to add only some of those Huawei suppliers to the entity list, with the notable omission of ChangXin Memory Technologies Inc., which is trying to develop AI memory chip technology.
