STORY: Beijing has told Chinese companies to stop using U.S. and Israeli cybersecurity software.
That's according to sources who spoke to Reuters.
They said authorities banned around a dozen firms from the country due to national security concerns.
Trade and diplomatic tensions continue between China and the U.S.
And Beijing wants to replace Western-made technology with domestic alternatives as both sides compete for tech supremacy.
Sources said Broadcom-owned VMware, Palo Alto Networks and Fortinet are among the U.S. companies whose software has been banned.
They also said Israel's Check Point Software Technologies was prohibited.
Reuters wasn't able to establish how many Chinese firms received this notice.
The sources added Chinese authorities were concerned the software could collect and transmit confidential information abroad.
Chinese regulators hadn't responded to requests for comment at the time of publication.
The four companies also didn't reply to Reuters queries.
