June 8 (Bloomberg) -- China has told personal-computer makers to offer software that blocks some Web sites, a spokeswoman for Hewlett-Packard Co. said.

“There are two options offered; either you pre-install them into the machines or it can be a drop-in box, which means you can put it on a CD and drop it into the packaging box,” Liana Teo, a Singapore-based spokeswoman for Hewlett-Packard, said by phone today.
