Who Wants to Supply China's Surveillance State? The West

The surveillance-equipment market in China was valued at $6.4 billion last year, according to IHS Markit . China is a big buyer of surveillance technology as Beijing steps up its efforts to better monitor its 1.4 billion people. That is providing a boon for equipment makers, who are looking to export their gear abroad. But it has also sparked concern from rights activists about how the authoritarian government is using the souped-up "Big Brother" technology. Seagate Technology PLC, Qualcomm Inc. and United Technologies Corp. were among the foreign companies to show their wares at the 16th China Public Security Expo, where prospective customers included Chinese police, government officials and businesses.
