That would be big

Trump and Xi

That's not a good sign for trade talks.

Bloomberg reports that the White House is discussing ways to limit US investors portfolio flows into China in a move that would be akin to capital restrictions.

It would be a major escalation in the trade war.

They're also considering de-listing Chiense companies from US exchanges, examining limits on the Chinese companies included in stock indexes managed by US firms.

The report says Trump has given a greenlight to the discussions but that any plan would be subject to his approval.

This sounds a bit like a leak to put pressure on China but the trade is to de-risk and ask questions later. Chinese stocks are getting hit particularly hard.

I find it hard to believe that we're headed towards a true, lasting trade deal when this kind of thing is on the table.
