I am a shareholder of SMVI, and have not read anywhere about a contract, or even negotiating with China. I think you could be dreaming here, but of course it is a future possibility.
There are many companys with the same type of product trying to come out, and grab part of that massive market. When I invest in particular sector I think has great potential, I try to buy the top 2 or 3 stocks in that area, with the best product, management, and has the budget to get the product released that I can find out about.
One other company I own stock in with simular product is from the company called Save the World Air, ticker sybol "ZERO". They have already have signed a large contract with a OEM from China.
This was just my opinion. Do your own due dilegence, and seek expert advice.
