South Korea said its technology firms will provide some semiconductor data to the U.S., following a request by the Commerce Department for companies in the supply chain to provide information on inventory and sales of chips.

South Korean firms are preparing for a "voluntary submission” of relevant information, the Finance Ministry said in a statement on Sunday, adding that its tech giants have been negotiating with the U.S. on the extent of data to be submitted. It didn’t elaborate.

The U.S. Commerce Department in September asked companies in the semiconductor supply chain to fill out questionnaires by Nov. 8 seeking information pertaining to the ongoing chip shortage. While the request is voluntary, Commerce Secretary Gina Raimondo warned industry representatives that the White House might invoke the Defense Production Act or other tools to force their hands if they don’t respond.
