In the South China Sea and underneath the South China Sea, of course, there's a lot of raw materials. There are very rich fishing grounds there, so there are some economic concerns in the South China Sea as well.

For a thousand years, Vietnam was a part of China. And that thousand years is punctuated throughout by rebellions from Vietnam.

From the United States, Vietnam is looking for two things. One of them is a very stable and continuing to expand economic relationship. Secondly, they would like to see the United States remain in the - Southeast Asia, acting as a balancing power to balance out China.

Vietnam is no longer a war, it's a country. I think that that's very important to understand. And the Vietnamese - last time a poll was taken, somewhere above 80 percent of Vietnamese people have a very positive outlook towards the United States.

And I think that Vietnameese see the United States as a source of markets, as a source of technology and as a source of this balancing power relationship with - against China. They - the Chinese and the Vietnamese have always had a very suspicious relationship of each other.

We can choose our friends, but we can't choose our neighbors.
