Williams has not denied reports it intends to sell its hydraulic systems and gearboxes to HRT in 2011.
The report emerged in Korea at the weekend, after the famous British team had in September admitted to receiving "enquiries" from other teams about its technical expertise.
"The status quo has not materially changed at the moment," a spokesman told us on Monday.
"We have publicly confirmed that we are amenable to supply elements of our drivetrain technology to other teams, but as yet we have not reached hard agreement with any customers.
"Of course we will make an announcement - or announcements - if and when we enter into any supply agreements," the Williams official added.
