I find you willing to defend any country's claim over China's even when you should have just as much of a problem, in fact sometimes more, with their politics. As far as Vietnam being concerned, they have been hostile towards China for some time so it makes perfect sense.Viet Nam is VERY concerned. China has been encoraching on their EEZ and claims a significant amount of maritime territory that rightfully belongs to Viet Nam.
Taiwan has no basis to claim an encroachment on its territorial waters because it remains legally a province of China even by its own laws. Aside from that what you are talking about from what I can tell is basically disputed waters.Similarly, there have been encroachments by China on the territorial waters of South Korea, Japan, Taiwan, the Philippines and even Indonesia. All of these states are concerned with the prospect of China's rise militarily and what it means for their own security.
What you are talking about, especially the garbage about North Korea, does not present a serious problem for ties between South Korean and China nor do I think it has any significant influence over public attitudes. While certainly most countries in the region have reservations about another country becoming more powerful militarily from what I can tell their attitude is not serious in most cases.All of them have serious reservations, EVERY SINGLE ONE OF THEM. South Korea was the one holdout for a while, but events over the past year (the sinking of a South Korean naval vessel by the PRCs satellite in North Korea and multiple encroachments on ROK territorial waters by PRC vessels among them) as well as the dispute over the historical kingdom of Goguryo and Balhae have caused considerable concern in South Korea.
The person who claims on one hand to only be criticizing the government but then clearly attacks the Chinese people as a whole has a lot less credibility. I am at least being honest about where I stand. What I am saying is that I have seen no indication of the kind of picture you are painting. Certainly there are some negative attitudes towards some countries, particularly towards their governments, but the way you talk about it is just obvious hyperbole from what I have seen. You can say as much as you like that it is because I am uneducated, but I think the real intellectual failing here is with you as you seem to only be capable of seeing things through a Sinophobic spectrum while disregarding all evidence suggesting your fears are inflated.You haven't met anyone from China in person yet you claim to understand them so well... Let me remember this fact when you try to convince us that you understand the Chinese so well. You have no basis for knowledge in this area. I have heard college lectures (that I was not supposed to hear) regarding China's relations with other countries. I have seen their response to every little slight. I have seen their lies regarding the U.S. when the U.S. accidently bombed their embassy and saw first hand the anti-U.S. demonstrations. I remember the anti-Japan demonstrations a few years ago after China lost the Asian Cup Final to China. You really do NOT understand what is going on over there. You have no credibility on this WHATSOEVER!!!
One can hardly expect attitudes to be entirely positive between any two countries. Look at how the European members of this forum interact with American members. You will find there is plenty of hostility there even though it would seem to be without any serious basis.
China isn't going to start a war to take control of the islands. Of course, any situation where military power is being increased in a region creates the potential for conflict so the probability of war will increase.Against a US carrier, they don't add up to much, but against a nation without much in the way of aircraft, they provide a striking force. Try the Spratly Islands. Major oil field and they are claimed by China, Vietnam, Philippines and Indonesia. Having a carrier around helps with keeping them when you move in the occupation forces and start drilling a well head and a pipeline to China.
