This article in the FT is interesting in that it highlights an area under review by many liberal western regimes which is whether and to what extent foreign investment should be regulated.  The focus of the article is Germany and Chinese investment into the German flagship automotive company, Daimler.

The US has indicated that it is looking to toughen US foreign investment rules amid growing concern regarding ownership of US high-tech companies as is evidenced by Donald Trump's recent blocking of the Broadcom deal on national security grounds.

In the UK, the government is currently midway through consultation on changes to the foreign investment rules although this may be delayed by Brexit and its implications.  A UK outside of the EU will need to strike a balance between promoting foreign direct investment and striking trade deals and security interests in a world where strategic protectionism appears to be on the increase.
