For those who had the same initial reaction as I did regarding Wind, the paywalled WSJ article specifically mentions "foreign think tanks, research firms and other nonfinancial entities" being unable to renew rather than institutional investors. Yeah, few foreign investors will go deeper than KWEB/FXI or ADRs/HK-listed shares but it would be saddening to impair those who remain interested in investing in onshore equities
Looks like to me that China has finally decided that the Cold War (and very likely a hot war) is inevitable. Zero reason for China to continue allowing the West to datamine China for economic and military exploits when we are all hurdling towards a clash.
The move came after China revised its Cybersecurity Review Measures in February last year to "strengthen national data security." At the time, the internet watchdog said CNKI contained sensitive information about China's major research projects and technological development.
