You answer my question as if it is self-evident; however, I'm pretty well informed in this area, and I'm not aware of any overt restrictions placed by China and/or India on foreign investment/trade.
To the contrary, China/India have experienced multi-billion capital investments from Japan, the US and EU. The net result is they import a huge amount of capital goods from those source countries as well.
If you can back-up your assertion that they have imposed trade restrictions, then you would go a long way towards convincing others to perhaps impose relatiatory tariffs.
If you can't, then you have a very weak position. I already know the answer, and so do the Dem/Repub leaders, which is why you aren't seeing any calls for restrictions.
There aren't any unfair trade policies holding back Americans. It's a pure economic shift were technology and service/skill transportability have conspired to create a unique situation where an established market is being rapidly displaced by the competition.
Unless you can back up your assertion, then you're advocating trade restrictions with no previous basis (according to Adam Smith and others) other than protection for protection's sake.
