Many manufactures are moving to Vietnam

I am working in shipping biz. I saw that many manufactures are moving their factories to out of Indonesia. Mostly their chose Vietnam as their new plant. Some that already relocated are Sony, Kacang Garuda (New factory), Mattel (will be soon). Yach, of course Vietnam give the felexibility for manufactures in do export/import policies such as waiving of port charges (Terminal Handling Charges), minimize of transport charges. It's just like a heaven for Japanesse or Korean companies to develop their money. Sometimes, i just think what the end of this scene ?
Shall all of foreign manufatures withdraw their investment and move to Vietnam ? or how long Vietnam government can afford this policies ?
Last time, i had a meting with my customer in Cibitung MM2100, he emphasized that if this condition still continues, at the end we would have problem with our children fr getting jobs.

It's possible, of course ... we just hope that it will be concerned of our government and house of reps to take a look into this fenomena.
