The story of US-China relations "has the potential to be one of genuine accomplishment. There is literally no limit to its possibilities," he said. "That's good for the United States, and that's good for China. The CPE is an investment, and it's an investment that I'm convinced will continue to pay dividends for all of us."

On sports, there will be new exchanges between athletes, which will include fencing training camps in both countries, and sports exchanges in volleyball, snowboarding, water polo and basketball, according to Richard Stengel, undersecretary of state for public diplomacy and affairs. In 2016, the Beijing Sport University will cooperate with Springfield College's third sports symposium, he said.

The two countries also will cooperate on the arts, including on a joint film project currently being filmed in China by acclaimed director Zhang Yimou, starring American actor Matt Damon. The film is the largest film entirely shot in China, and will "connect people and foster mutual understanding", Stengel said.

Zhang said via video during the session that film will give viewers a "window into new places that they may have never seen before".

On health issues, Liu recounted China and the US' cooperation during the outbreak of the Ebola virus in west Africa. The two countries shared real-time information and technological guidelines and standards when China's teams arrived in Liberia.

"These touching stories and fruitful results demonstrated the passion of people from different walks of life, revealed the charm of the CPE, and injected vitality into the China-US relationship," she said.

Liu said that seeing all the productive outcomes of the CPE made her even "more confident of the prospect" of the exchanges that the two countries have engaged in, and she said she believes that the magnitude and depth of cooperation between the two countries is unprecedented.

"More than 30 years ago, China's reform began, and so did normalization of relations," Liu said. "In the coming 30 years, China will strive to meet its goals of building a harmonious modern country. We will make sure that Chinese people will have better living conditions so they will live happier lives. The Chinese dream is about peaceful development and win-win cooperation, which is closely related to the American dream."

Liu said that "for China and the US, respecting each other, pursuing win-win cooperation, and (the) building of new model relations will not only bring benefits to two people but will contribute to world peace. China will only open wider to the outside world, and China's environment will become fairer, more transparent and predictable."
