US President Barack Obama will conduct in-depth meetings with President Xi Jinping when he attends the G20 Hangzhou summit in early September, the White House announced on Aug 18.

The two leaders will meet in Hangzhou, East China's Zhejiang province, where the G20 will be held for the first time in China, to discuss "a wide-range of global, regional and bilateral issues", the White House said in a statement.

In China, Obama will participate in his final G20 Leaders' Summit, where he will emphasize the need to continue building on the progress made since 2009 in advancing strong, sustainable and balanced global economic growth.

He will underscore the importance of G20 cooperation in promoting a level playing field and broad-based economic opportunity.

This trip will highlight "Obama's ongoing commitment to the G20 as the premier forum for international economic cooperation as well as the US rebalance to Asia and the Pacific", the White House said.

It will be Obama's 11th trip to Asia since he took office in 2009. The trip from Sept 2-9 also includes a visit to Laos. Obama will be the first US president to visit Laos, where he will participate in the US-ASEAN Summit and the East Asia Summit.

Stephen Orlins, president of the National Committee on US-China Relations, said in an interview with Xinhua that the G20 Summit could help deepen mutual understanding between China and the US and boost bilateral ties.

"Every time that an American president visits China, it is a benefit to US-China relations. Every time that a Chinese president and an American president meet, it is a benefit to US-China relations," Orlins said.

Orlins said that as the G20 host, China has the opportunity to set the tone and agenda for the meeting and help all participants reach an important consensus.

It is "very much up to China" whether the G20 summit can produce some really encouraging outcome,"Orlins said. "I think China is going to need to lead. I think China in a lot of ways can lead," he said.

"I think China being the host of the G20 is very much a kind of statement that China is now one of the most important economies in the world, and it is terrific that it is being able to do it," Orlids said Orlins.

Orlins said that he believes the world needs to seek new growth engines from innovation and clean industries, and that China as a global leader in both fields should steer the Hangzhou summit to achieve some breakthroughs. "We need to see more innovation that can be shared globally, and we need to see more movement towards industries which emit less carbon. I hope that's what comes out of the G20," he said.
