You still don't understand what I talk about? I repeat the marine border has not confirmed, it needs talk or negotiate. But look at those country's attitude. I don't know if they don't want to negotiate with China, or the USA threat them not to negotiate. Who knows? After we confirm the border, will there be disputes and conflicts? The guys always say China is aggressive and invade them, the border has not confirmed, how to say invade? If we claim Palawan, and want to occupy it, that's aggressive and invade, because Palawan has confirmed the Philippines' territory. Can you understand what I say?
Another example, China and Vietnam even once had a war on land border before the boundary confirmed. ( I regret it. )But now the boundary area is peace and mutual trade is huge. Why? After year 1991 confirm the border, year 2000 wholly measured and put landmark, there are no disputes anymore. Nowadays, those nation always refuse to negotiate and confirm boundary, what can we do? We can just estimate what those lovely neighbors want: China develop navy, defeat USA, then they come to talk. Is my guess right or wrong, I don't know what's in your guys' mind.
