President Obama: I want to welcome Vice President Xi to the Oval Office and welcome him to the United States. This is obviously a great opportunity for us to build on the U. S.-China relationship, but also an opportunity to return the extraordinary hospitality that Vice President Xi showed Vice President Biden during his recent visit to China.

As I indicated during my recent visit to APEC and the East Asia Summit, the United States is a Pacific nation. And we are very interested and very focused on continuing to strengthen our relationships, to enhance our trade and our commerce, and make sure that we are a strong and effective partner with the Asia Pacific region. And obviously, in order to do that, it is absolutely vital that we have a strong relationship with China.

So, Mr. Vice President, I hope you have a wonderful visit while you're here. I'm sure the American people welcome you. I'm glad that you're going to get an opportunity to get out of Washington. I know you'll be visiting Lowa, which you visited many years ago when you were governor. And I understand you're also going to Los Angeles and maybe even taking in (观看) a Lakers basketball game. So I hope you enjoy that very much.

I want to extend my deepest welcome to you, and look forward to a future of improved dialogue and increased cooperation in the years to come.

   I know we don't have many serious talks, but now that I am on the edge of being an adult, I feel that

you need to know and understand me. During the past nine years that we have been in America, I have

grown greatly, changed from that wide-eyed and scared little girl to a proud and brave young woman.

The change wasn't always smooth, and I wasn't always patient, but you were both always understanding.

And through your understanding I have learned.

   I have learned from you. Dad, you wake up every morning to go to the steel plant, where people don't

speak your language and you don't speak theirs. I know that if you were in Vietnam, you would be

comfortably surrounded by friends. But you are here in America, doing what you don't like, and through

that, you are teaching your children the power of persistence.

   I have learned from you, Mom, you cook nice Vietnamese sour soup and fish, wait up at nights for

your daughters. When I see you pacing back and forth because your daughters aren't home yet, I cry

because I see so much pain in your eyes, and through your pain I learn the meaning of home a sanctuary

that I will always be able to turn to.

   Through all your sacrifices I learn the essence of being human. I learn to love. I find that this love leads

me to you, to the home, to the fact that I am Vietnamese-American. The dreams that you have taught me

slowly begin to take shape as I walk down the college path, step into the adult world and adventure out

of your world. Wherever I go, I carry my past with me, knowing that you will always be there behind me

and I will always come back, because you are where my home is.
