Building barriers and pushing for decoupling would harm others and benefit no one, Xi said in his keynote speech on Tuesday at the annual Boao Forum for Asia, China's answer to the Davos conference.

China has longed called for reforms in global governance in which the perspectives and values of multiple countries are reflected, including its own, instead of a few major nations.

Beijing has repeatedly clashed with the biggest stakeholders in world governance, particularly the United States, over a range of issues from human rights to China's economic influence over other countries.

"The world wants justice, not hegemony," Xi said.

"A big country should look like a big country by showing that it is shouldering more responsibility," he said, without identifying any nation.

On Friday, US President Joe Biden held his first face-to-face White House summit since taking office with Japanese Prime Minister Yoshihide Suga, with China topping the agenda.

In a joint statement, both leaders said they "share serious concerns" about the human rights situation in Hong Kong and China's Xinjiang region, where Washington has said Beijing is perpetrating a genocide against Muslim Uighurs. China has denied abuses.

In an apparent show of US-Japan economic cooperation to the exclusion of China, Biden said the United States and Japan would jointly invest in areas such as 5G technology, artificial intelligence, quantum computing, genomics and semiconductor supply chains.
