This is an English news sentence about Foxconn. I have listed a few key points if you don’t understand English. Please give some advice from experts.

1. Impose means "to impose" when used as a transitive verb. Here it can be literally understood as "forcibly freezing recruitment". The usage is to impose something.

2. Across here means "covering", and the original meaning is "through". The literal meaning is "through most of the factories", so it can be understood as "covering most of the factories". It has nothing to do with the previous impose, which are two independent words, and there is no phrase impose sth freeze across.
