Most of their points are rather accurate, although there are
some that just seems misguided and without basis. Of course they
fail to note that international relationships are not as simple as
they percieve, neither did these students realise
that had the Chinese government persisted with their hardcore
communism policies prior to the 1990s, they might not be surfing
the net today, posting comments to flame Singapore. Which was why
our government refused to conduct diplomatic relationships in line
with our anti-communism policy back then.
Also, I fail to see what's there to be proud of when everything
they "manufacture" (in terms of weaponry) are reverse-engineered?
STK might not be as active as NORINCO but we dun have an arms
ambargo imposed on us. 
Last point, their people are not united as well. Like what some
said, northerners look down on southerners, city folk look down on
country folk, etc. One cannot expect them to look kindly on
overseas chinese, no matter how much "respect" we give them.
