The two leaders said the United States will take China's trade concerns seriously and would like to seek proper solutions through dialogue.

In addition, the United States welcomes foreign businesses, including those from China, to invest in the United States and the United States is also willing to discuss with the Chinese side the possibility of Chinese enterprises investing in US infrastructure projects, the two leaders said.

During Xi's visit, related departments of the Chinese, US governments signed several cooperation documents on investment, agriculture, inspection and quarantine.

Firms from the two sides also signed trade and investment deals covering the areas of electronics, telecommunications, farm produce, energy, environmental protection, mechanics, chemical industry, pharmacy, among others.

Third, Xi's trip to the United States has deepened China-US friendship and promoted local-level cooperation.

During the five-day visit, Xi made extensive contacts with Americans from all walks of life, engaging himself in the promotion of China-US friendly ties and the consolidation and enlargement of the social and public basis of furthering China-US ties.

In the small town of Muscatine in Iowa, which he visited 27 years ago as an official of China's Hebei province, Xi reunited with a dozen of his old friends for a teatime chat.

At a luncheon hosted by friendly groups in Washington, Xi told a moving story about how he facilitated a trip of an American lady who was trying to fulfil her late husband's wish of revisiting Kuling, his childhood home in Fujian Province in southeast China.

These two episodes have become impressive moments in China-US friendship.

Xi encouraged people of both countries to make new friends and keep old ones to deepen friendship.

At the International Studies Learning Center in Los Angeles, Xi talked to American students face to face.

"Young people are the future of a nation," he said.

Xi called for mutual understanding and friendship between youths of the two countries. He said the two countries should enhance cooperation in culture and education to cultivate talent for the development of both nations and for China-US cooperation.

Xi also held cordial talks with representatives of overseas Chinese and Chinese students in America, encouraging them to actively serve as a bridge in advancing China-US friendly exchanges and cooperation.
