The Qingchengshan high school, located in the Dujiangyan city near the province's capital of Chengdu, was flattened by the 8.0-magnitude devastating Wenchuan earthquake. And the post-quake assistance from the U.S. National Basketball Association (NBA) added a bond between the school and the United States.

As NBA helped the school build four brand-new basketball courts, the two leaders watched a basketball training by a 30-member team upon their arrival.

Xi and Biden then stepped into the teaching building to talk with a group of students.

"We have a mutual interest," and "President Obama and I want to see a rising China, we don't fear a rising China," Biden said when answering a question by a student on how he viewed China's changes in recent 30 years.

The two leaders also visited the city of Dujiangyan, which was renowned for its Dujiangyan Irrigation System, the world's oldest functioning irrigation project, dating from 256 B.C.

Earlier Sunday, Biden delivered a speech on U.S.-China relations at Sichuan University.

Biden arrived in Beijing Wednesday evening for a six-day official visit to China as a guest of Xi. He will leave Chengdu for Mongolia on Monday.
