China's determination for reform and opening-up is firm, Xi said.
"It is not a problem of whether to open up or not, it is a problem of how to deepen the opening-up. It is now impossible to shut the door. But we also hope that foreign countries also deepen their opening-up to China, and it should be a two-way street."
Xi said China's development benefits the world, and China's win does not mean others will lose or earn less. "It's mutually beneficial," he said.
Many companies at the meeting signaled their willingness to help China's social development.
Andrew Forrest, chairman of Australian miner Fortescue Metals Group, said the growth of his company benefited from selling iron ore to China. His company will increase its investment in China and be more involved in China's social development.
The Japanese business community called for the development of the strategic and mutually beneficial relationship with China and for promoting trade and economic cooperation, according to Koji Miyahara, chairman of Japanese shipping giant Nippon Yusen Kaisha.
For Asia to lead world growth, "it requires building mutual trust and cooperation to realize common development", Miyahara said.
China's promise to build an open and fair market shows its responsibility and commitment to the world, as global protectionism is picking up amid the economic slowdown, said Jiang Yong, a researcher on global economics at the China Institutes of Contemporary International Relations.
"It also conveys China's confidence," he said.
