To tell the truth, I don't agree with China 9 dash line too. Not because they crossed my country ZEE, but because that is too greedy. My personal political view is this. China should withdraw their 9 dash line claim, and stay on their de facto islands in Spratly and Paracel. But, it is also aim to other claimants (Pinoy, Vietnam, and Malaysia) that they should stick to what they owned until now. And not get more for themsleves.
In my personal point of view, all claimants are greedy. So, I don't want to get trapped into their political ambition to get more for themselves. Hopefully you can see this too. Peace can only be achieved if everyone stick to what they have already and not get more for themselves. Because my personal political view dictate that everyone should stay on their de facto islands, and not get more for themselves, I consider Paracel belong to China. And because 981 is located near Parace, then you know what is the answer. so you now can see my point of view of this matter. It's not because I support China in this. But because I favor on the status quo.
Btw, about Philiphine scarborough Shoal? (is it right? the name?) I think that China should return it to Pinoy. I don't think that China won't do this. Historically, China did cede some of their disputed territory in favor for peace. Just look at what they did with Russia and Bhutan (is it right, Bhutan?). They even gave half of the Korean sacred mountain to North Korea. And (if the rumor true), they return some Vietnamese land that they've taken from the Viet in their Sino- Vietnam war. So I think that what China want is just bullying Pinoy.
And for this oil rig 981, do you believe that it actually drill? I believe that it is more of a stratagem than actually a mere violating Vietnam ZEE.
Btw, I love Japanese Ramen
