C’mon, Perry; the Chinese helpful to us? In Korea, maybe, only because they don’t want the superior (militarily, technically, economically, politically, morally) Japanese to rearm. The Chinese helpful in regard to Iran? Yes, they are; helpful TO Iran, shipping them Silkworms (antiship missles) and the like.
I agree with sdns: China is heading for a big fall due to its wobbly banking system and the upcoming fall in demand (e.g., from the U.S.) for its products.
My sense is that India, with its British-bred democracy, will overrun China as the emerging power of Southeast Asia.
