STOP wasting your time debating on something that is so OBVIOUS.
China will continue to be the world factory for another 30 YEARS easily. She is now on the next stage of industrialization and moving to the next level of manufacturing where nations like Japan, Taiwan South Korea, etc. All these nations despite of their skilled workers are losing out because of domestic market support.
Can Vietnam produces hi-tech products like AIRLINERS, High Speed Trains, satellites, etc. Let assume they can but who will ever buy them. Most the core electronics proprietary PCB continue to be imported directly from China. Same goes for many ASEAN nations including Philippines.
There are over 2 million factories in PRC. Many of them which are in fact Chinese firm themselves are merely relocating their SWEATSHOP function to the lower costing nations.
Vietnam is already facing the obvious problem - rising cost. It has just increased its worker pay by 12.5%.
To be a world factory, one of the requisite is a HUGE HOME DOMESTIC MARKET which is visibly missing factor in everyone of them including Japan e.g. Toyota lost its crown as the world biggest car maker to VW because of the political spate over Diaoyutai.
I won't waste my time debating in circle with the khmer krom nationalistic trolls from Vietnam and others.
