Foreign direct investment in the PRC has fallen to $20 billion in the first quarter of this year, compared with $100 billion in last year’s first quarter. This is strongly influenced by, if not a direct result of, PRC President Xi Jinping’s “security” policy that explicitly targets foreign investors as likely spies.

A Xi-led campaign this year has hit Western management consultants, auditors, and other firms with a wave of raids, investigations, and detentions. Meanwhile, an expanded anti-espionage law has added to foreign executives’ worry that conducting routine business activities in China, such as market research, could be construed as spying.

There’s this, also:

A senior official in a county of southern Guangdong province, which earlier this year set a goal of attracting nearly $300 billion in investment in the next five years, told a visiting American trade group recently that the county would reward any US corporate “decision maker” investing there 10% of the value of the promised deal, according to people briefed on the matter.
The trade group turned down the county official’s offer, which in the US would constitute an illegal bribe, the people said.

The Guangdong senior official knew his offer would be a bribe under US law, and he made the offer anyway.

There is no investment in anything in the PRC that’s worth the political, or the legal, risk.

More than that, as long as the PRC continues its genocide (in the present time against the Uighurs, but those people have not been the PRC’s only targets), it’s morally impossible to invest in any way, in any thing, in the PRC.

That’s apart from, and in addition to, the national security risk presented by any trade with or within the PRC, given its present control over our supply chains, particularly in critical items such as the rare earths it embargoed from Japan for a time and its current bar of gallium and germanium export to us.

We, and the West at large, have nothing to gain from investing in or trading with this enemy nation, and everything to lose.
