More than 150 countries and over 30 international organizations have signed Belt and Road cooperation documents. Based on the principle of "planning together, building together and benefiting together", Belt and Road cooperation has extended from the Eurasian region to Africa and Latin America.

It transcends differences between civilizations, cultures, social systems and stages of development, and has opened up a new path for exchanges and cooperation among countries, Xi said.

While calling for promoting win-win cooperation, Xi urged countries taking the lead in economic development to give a hand to their partners who are yet to catch up.

"We should all treat each other as friends and partners, respect and support each other, and help each other succeed," he said. "Viewing others' development as a threat or taking economic interdependence as a risk will not make one's own life better or speed up one's development."

Xi emphasized that the BRI aims to promote connectivity, mutual benefit and common development. "Ideological confrontation, geopolitical rivalry and bloc politics are not a choice for us."

As part of its efforts to expand opening-up, China will establish pilot zones for Silk Road e-commerce cooperation and enter into free trade agreements and investment protection treaties with more countries, Xi said. "We will remove all restrictions on foreign investment access in the manufacturing sector," he added.

China will further advance high-standard opening-up in cross-border service trade and investment, expand market access for digital and other products, and deepen reform in areas including the digital economy, intellectual property and government procurement, the president said.

He noted that China will hold the Global Digital Trade Expo annually. "In the next five years, China's total trade in goods and services is expected to exceed $32 trillion and $5 trillion, respectively."

A total of 458 outcomes were delivered during the forum, including a series of international cooperation initiatives and an array of cooperation agreements, according to a statement issued after the event.

Among them, China also put forward the Global Initiative for Artificial Intelligence Governance to promote sound, orderly and secure AI development, the statement said.

Speaking at a news conference after the forum on Wednesday, Foreign Minister Wang Yi highlighted the outcomes of the forum.

He said that these demonstrate that peaceful development and win-win cooperation conform to the general trend of the times and people's aspirations, while Cold War confrontation and decoupling are against the tide of history and are doomed to fail.
