Those who complain that nothing has been done about China seem to be unaware of export control, Wassenaar Arrangement and CFIUS.

Which are exceptionally narrow and target too narrow of technologies to make much difference from a GDP perspective.

I used to work CFIUS issues for the DoD and can tell you that the government preventing tech from being exported when both parties (developer and acquirer) want to share basically never happens.

Governments think of technology as products, but of course it is people that possess knowledge. Unless you cut off connections amongst people, eventually knowledge will diffuse.

They may be protectionist but their market is still 1.4 billion strong.

What does that even mean?

That is like me saying something like this: they may be 1.4 billion strong, but most me are considered unhappy and sexually frustrated by policy design.

>China has many millions more men than women, a hangover of the country's one-child policy, which was overturned in 2015, though its effects will last decades more. The gender imbalance is making it hard for many men to find a partner – and the gap is likely to widen.

>By 2020, it’s estimated there will be 30 million more men than women looking for a partner. In his book, The Demographic Future, American political economist Nicholas Eberstadt cites projections that by 2030, more than a quarter of Chinese men in their 30s will not have married.

So 2.14% (30 million / 1.4 billion) of the males are potentially sexually(?) frustrated as monogamy is not an easy option for them, how is this relevant to the discussion exactly?
