But they bring in the sweet Dollars too. That's why I'm hesitant to shut them off completely(Technology firms). Chinese government, to be fair here, gets tax from these companies that they use for public welfare, infrastructure and military.I agree 200%, Wall St in China is as much a risk as there are certain benefits.
Also their people are infiltrating Chinese firms. Didi is an example, many of Didi's directors and C-level folks were helicoptered in from Wall St investment banks, typically well-connected Chinese kids from Lvy league who have sold their souls to satan. But if Didi's recent episode indicates anything is that Beijing regulators are still on top of things and will cut their balls off if required.
For financial firms like GS, Br etc the risks are way more with little benefits. I think, long term, they are a BIG threat. We must follow their actions and how China deals with them closely. But, if we are to argue FOR them, I think these Financial companies will force Chinese banks and private companies to improve in their services and quality. Competition is good. Also, China is creating points of pain and leverage here as these companies would lobby for better China relations ( but this is only a hopeful wish. Geopolitics aren't based on wishes. There are many reports that Trump's trade war was pushed behind the curtains by Qualcomm, Intel etc which had huge ties to Chinese electronics industry).
However, the first step, as some members mentioned, would be to create clear, concise and robust framework towards regulation for Data privacy, localization and National security.
