Hi Ted, I am not 100 percent sure of the following but I believe the reference to Amtronics India being the JV is incorrect. It is a subsidiary of Amtronics cc to do business in India and pay taxes in country. That's what makes sense to me.
Technically the quote from the Amtronics India website should say " Amtronics India" not just "Amtronics".
Qamronics India PVT is the joint venture formed by Amtronics (India) and Assam Electronics Development Corporation Ltd, (AMTRON) which is the State-owned Public Sector Undertaking of the Government headed by M.K.Yadava.
